Plastic-Bodied Industrial Exhaust Fans

What is a plastic-bodied industrial exhaust fan?

Plastic-bodied industrial exhaust fans are high-flow exhaust fans with a casing — and often blades — made from engineering plastics. Because plastic does not rust like metal, it offers a long-lasting solution in humid, steamy, or mildly corrosive environments. Primary applications include laundries, pool and spa areas, greenhouses, animal shelters, food processing facilities, and workshops where chemical vapors are present.

Advantages

• Corrosion resistance: No rusting due to moisture or steam.
• Lightweight: Easy to install and transport.
• Chemical resistance: More resistant to many mild acid and alkali vapors than metal-bodied alternatives.
• Easy cleaning: Smooth surfaces can be cleaned by washing.

The model in this category is described as suitable for environments where acidic vapors may be present, as stated in the product name; compatibility with the specific chemical used should be verified in the product information.

Selection and use

The fan diameter and flow rate should be selected based on the room volume and required air change rate. Plastic-bodied fans are not suitable for conveying high-temperature air; the temperature limit should be checked for hot exhaust applications. In environments with flammable vapors, only explosion-proof fans must be used. The motor's protection rating against moisture and dust must be appropriate for the environmental conditions.

Installation and maintenance

The fan should be firmly secured to the wall opening, and excessive tightening force must not be applied to the plastic casing. A rain cover and louver on the outside are recommended. The blades and casing surfaces can be cleaned by washing regularly; electricity must always be disconnected before cleaning.

Frequently asked questions

Is the plastic casing resistant to sunlight?

The UV resistance of plastics used outdoors varies by material. Where possible, protect the fan from direct sunlight.

Which chemical vapors can it be used with?

It can be used with mildly corrosive vapors. Compatibility by chemical type should be verified in the product information.

Does a plastic fan work in high temperatures?

High temperatures can damage plastic. Do not exceed the temperature limit.

Is it more durable than a metal-bodied fan?

It is more resistant to corrosion; metal-bodied fans are more robust against mechanical impact.

Can it be used in a pool area?

Models suitable for humid and chlorinated air can be used in pool areas.

Is there a metal-bodied alternative?

Yes; see metal-bodied industrial exhaust fans.

Is a plastic-bodied exhaust fan lightweight?

It is lighter than metal-bodied models, which makes installation and transport easier.
