Air Bellows Operate Equipment in Hazardous Environments

The Presair air switching system is found in hazardous environments where equipment needs to be running, while isolating the user from the electrical connection, such as near water. Common applications include garbage disposals, sewer cleaners, or outdoors. Recently, we discovered a new application where the air bellows paired with an air switch operate screen printing washout booths at a school district. When the air bellow is pressed it sends a burst of pressure to an air switch, which contacts close turning on the inspection lights. The lights remain on until the air bellow is pressed again to turn the lighting off (alternate action). The air switches are UL listed for up to 100,000 cycles, making this a safe, long lasting solution.

I’m sure OSHA would be much happier with them in our wet environment rather than the plain power strip we were using.

Air Bellow Switching System

Don’t risk an electric shock when you operate your equipment in hazardous environments!

You can mount the air bellow near the equipment and when you push the button, you force air through a long tube. The air trips the switch on the equipment, which completely isolates the user from the electrical, removing any risk of shock!

Presair offers a wide range of air bellows and air switches. Safe, versatile and easy to use, Presair’s electric to pneumatic converter box works with many different appliances, such as TVs, lights, computers, stereos, garbage disposers, drill presses, and scroll saws. The air switch box instantly converts any standard 120 volt grounded outlet to a switchable connection.
