An electric motor can run for hours without trouble only when you manage its heat properly. In many industrial motors, the shaft-mounted cooling fan plays an important role in moving air over the motor body and helping it dissipate heat.
When the original fan becomes cracked, damaged, worn out or otherwise unsuitable, replacing it with the correct motor cooling fan is important. A PVC or plastic motor cooling fan can be a practical replacement for compatible motors because these fans are lightweight and available in many motor-specific sizes.
However, choosing one is not simply a matter of matching the motor’s horsepower. The fan’s inner diameter (ID), outer diameter (OD), motor frame size, mounting arrangement, and shaft/keyway or nut-bolt configuration must also match. This guide looks at five PVC/plastic motor cooling fan options currently listed by Indian suppliers for different motor families and frame sizes.

1. PVC Motor Cooling Fan for 160-Frame Motors
The PVC Motor Cooling Fan for ND160-frame motors is one of the more clearly specified replacement options found during the research.
MSC Kolkata lists a 250 mm fan with 10 blades for a 160-frame motor. The listing identifies it as a shaft-mounted motor cooling fan and gives plastic as the material. It also identifies Crompton as the brand associated with the listing.
The supplier lists the price at approximately ₹600 per piece and a minimum order quantity of 12 pieces. The frame size is particularly useful here. Instead of simply ordering a fan because it is described as a “motor cooling fan”, a buyer can use the motor frame and physical dimensions to narrow down the correct replacement.
This type of fan may be relevant when replacing the cooling fan on a compatible 160-frame motor where the original component has been damaged.
Key details:-
- Motor frame: 160
- Fan size: 250 mm
- Number of blades: 10
- Mounting: Shaft mounted
- Material listed: Plastic
- Brand listed: Crompton
- Listed price: ₹600
- MOQ: 12 pieces
2. PVC Cooling Fan for CGL ND225 Frame Motor
For a larger motor, the CGL ND225-frame option listed by MSC Kolkata provides a different size category. The supplier lists this as a PVC cooling fan for a CGL ND225-frame motor, with a 300 mm fan size.
The listing specifies plastic construction, shaft mounting and 415 V AC, with the motor frame identified as ND225. The listed price is ₹1,999 per piece, with a minimum order quantity of six. The price difference compared with smaller motor fans illustrates why it is difficult to quote a single “PVC motor cooling fan price”.
The motor frame, physical dimensions, and specific replacement design can have a major effect on price. For a replacement, check the ND225 frame designation against the motor nameplate and the physical fan before ordering.
Key details:-
- Motor/frame: CGL ND225
- Fan size: 300 mm
- Material listed: Plastic
- Mounting: Shaft mounted
- Voltage listed: 415 V AC
- Type: PVC cooling fan
- Listed price: ₹1,999
- MOQ: 6 pieces
3. PVC Cooling Fan for Siemens Motor
Machinery & Spareparts Centre lists a PVC cooling fan specifically for a Siemens motor, with considerably more dimensional information than many generic marketplace listings.
The listed version is described as a 20 HP PVC cooling fan, with an inner diameter of 44 mm and an outer diameter of 200 mm. The supplier specifies virgin PVC as the material and lists the current price at ₹440. The ID and OD are particularly important when replacing a shaft-mounted fan.
Two fans can look similar while having different bore dimensions, and the wrong bore can make installation impossible or unsafe. For Siemens-compatible replacement parts, buyers should therefore compare the old fan and motor documentation rather than relying on horsepower alone.
Key details:-
- Motor application: Siemens-compatible
- Motor power listed: 20 HP
- Inner diameter: 44 mm
- Outer diameter: 200 mm
- Material: Virgin PVC
- Listed price: ₹440
4. PVC Cooling Fan for Marathon Motor Frame 160
Another frame-specific option is the PVC cooling fan listed for a Marathon motor. Machinery & Spareparts Centre lists a PVC cooling fan for a Marathon motor with frame 160, specifying a 42 mm inner diameter.
The current listed price is ₹400, compared with an earlier displayed price of ₹600 on the same product page. The listing is a useful example of why the motor frame and bore need to be checked together.
A frame number alone may not be enough when different mounting or shaft arrangements exist. The supplier also lists other Marathon cooling-fan products, including aluminium versions, showing that material selection can vary by application and motor requirements.
Key details:-
- Motor brand/application: Marathon
- Motor frame: 160
- Inner diameter: 42 mm
- Material: PVC
- Listed price: ₹400
5. 15 HP ABB PVC Motor Cooling Fan
For ABB-compatible applications, Aggarwal Moulding Works lists a 15 HP ABB PVC Motor Cooling Fan under its motor cooling fan range. The listing gives a 235 mm diameter, 40 mm size, circular shape and plastic construction.
The supplier lists the product at ₹130 per piece, with a minimum order quantity of 50 pieces. There is an important terminology point here. Although the product title calls it a PVC motor cooling fan, the detailed specification identifies the material simply as plastic.
If the material itself matters, it would be better for a buyer to confirm the exact polymer specification with the supplier. The supplier also lists an ABB M2BAX-type cooling fan variant separately. ABB’s own documentation confirms that the M2BAX is an IEC low-voltage motor family covering a wide range of frame sizes, so matching the exact motor frame remains important rather than assuming that every M2BAX motor uses the same fan.
Key details:-
- Motor application: ABB-compatible
- Power listed: 15 HP
- Diameter: 235 mm
- Size/bore listed: 40 mm
- Material listed: Plastic
- Shape: Circular
- Listed price: ₹130
- MOQ: 50 pieces
PVC vs Plastic: Why the Listing Can Be Confusing?
Buyers should pay attention to this. Indian motor-spares suppliers frequently use terms such as PVC motor cooling fan, plastic cooling fan and virgin plastic cooling fan in product titles. However, the detailed specification can identify the material differently.
For example, the Siemens listing explicitly specifies virgin PVC, while the ABB listing uses “PVC” in the product name but says “Plastic” in its specification.
Another supplier’s Crompton fan is specified as polypropylene. If the material matters for temperature, mechanical strength, or a particular industrial environment, ask the supplier to confirm the exact material before placing the order.
Things to Check Before Buying a PVC Motor Cooling Fan
1. Motor frame size
The frame designation is one of the easiest ways to narrow down the correct replacement. Examples from current listings include 160- and ND225-frame applications. Do not assume that a fan for one 160-frame motor will automatically fit every 160-frame motor.
2. Inner diameter or bore
The bore must match the motor shaft or mounting arrangement. The Siemens listing, for example, specifies a 44 mm ID, while the Marathon frame-160 listing specifies a 42 mm ID. Even a small dimensional mismatch can prevent correct installation.
3. Outer diameter
OD affects the physical clearance between the fan and surrounding components. The Siemens fan is listed at 200 mm OD, while the CGL ND225 version is listed with a 300 mm fan size.
4. Mounting arrangement
Check whether the fan is designed for a shaft, keyway, pin or nut-and-bolt arrangement. Suppliers themselves ask buyers for this information when identifying replacement fans.
5. Number of blades
Blade count helps identify a replacement, but it should not be the only selection criterion. The Crompton/ND160 listing, for example, specifies 10 blades, while other motor-specific fans have different blade configurations.
6. Motor manufacturer and model
If the motor is from Crompton, Siemens, ABB, Kirloskar, Marathon or another manufacturer, provide the supplier with the exact motor details. For ABB motors in particular, the M2BAX family spans numerous frame sizes and configurations.
How to Choose the Right Motor Cooling Fan
The safest approach is to treat the cooling fan as a motor-specific spare part, not a generic fan.
Before ordering, note down:-
- Motor manufacturer
- Motor model/type
- Motor frame size
- Motor horsepower or kW
- Fan inner diameter
- Fan outer diameter
- Fan thickness
If relevant,
- Number of blades
- Mounting method
- Keyway dimensions
If applicable,
- Original fan photograph
A clear photograph of the old fan, along with measurements of the bore and outside diameter, can make supplier identification much easier.
For replacement work, it is also useful to compare the original fan with the proposed replacement before removing or discarding the old component.
Common Applications
PVC and plastic motor cooling fans are used as replacement components in a variety of electric-motor applications.
Supplier listings cover motors used with:-
- Industrial machinery
- Motor-pump assemblies
- Pumps
- Compressors
- General-purpose electric motors
- Industrial equipment
- Manufacturing machinery
Exact suitability depends on the motor design and the replacement fan’s dimensions, not just the application name.
Frequently Asked Questions
What is a PVC cooling fan for an electric motor?
It is a fan mounted on or associated with an electric motor’s shaft and used to move air around the motor for cooling. Replacement versions are available in PVC and other plastic materials, depending on the manufacturer and supplier.
How much does a PVC motor cooling fan cost in India?
There is no single fixed price. The researched listings in this guide range from ₹130 to ₹1,999, depending on motor compatibility, dimensions and supplier. Some are sold with minimum order quantities, so the effective purchase cost can differ from the displayed single-piece price.
Can I use any PVC fan if the motor horsepower is the same?
No. Horsepower alone is not enough. The fan’s bore, outside diameter, motor frame, mounting arrangement and physical clearance should also match.
What information should I give a supplier when buying a replacement?
Give the supplier the motor brand, model, frame size, horsepower, fan ID and OD, mounting type and a photograph of the existing fan. These details make it easier to identify the correct replacement.
Are PVC and plastic motor cooling fans the same?
Not necessarily. Some Indian listings use “PVC” in the product title but describe the material only as plastic or virgin plastic in the specifications. If the exact polymer is important, confirm it with the supplier before ordering.
Are these fans available for large industrial motors?
Yes. Indian suppliers list motor cooling fans for a wide range of motor frames and power ratings, including larger Siemens-, ABB-, Crompton-, and Kirloskar-compatible applications. ABB’s M2BAX documentation itself covers motor frame sizes from 71 through 355.
Conclusion
A PVC cooling fan may look like a simple motor spare, but getting the correct one requires more than matching the horsepower printed on the motor nameplate. The most useful specifications to check are the motor frame, fan ID, OD, mounting arrangement, material and motor compatibility.
The five products covered here show how much these specifications can vary: from a 160-frame fan to an ND225-frame CGL fan, and from a 42 mm Marathon bore to a 44 mm Siemens bore. Current Indian listings also show wide price variation.
The five researched examples range from ₹130 to ₹1,999, but treat these as reference prices rather than fixed market rates.
If you are replacing an existing fan, the practical approach is simple:
- measure the old fan
- the motor frame
- mounting arrangement
- and confirm the dimensions with the supplier before ordering.
That small check can prevent an otherwise inexpensive replacement from turning into the wrong spare part.
