Ultimate Safety for Repair & Paint

Supplied Air Respirators by Allegro

One of the big dangers of repairing industrial materials and using urethane paints are the isocyanates in the paint. These are a serious health hazard for those working in industrial repair and painting. Others who work grinding metals or with hazardous particles in a confined space (like automobile or bath repair and refinishing) find traditional filters or cartridges don’t work as well because they aren't a match for the toxicity and volume of fine particles. Toxic repair projects in confined spaces are ideal for supplied air respirators (SARs), also known as airline respirators.

What is an airline respirator or SAR system?

The air pump supplies the clean breathing air, the hose delivers the air to the mask, and the mask assembly keeps the good air around your face while allowing you a wide, clear view of your work.

Why do painting and repair experts use them?

The beauty of the SAR system is that you can work around dangerous fumes or airborne particles, and still breathe the nice, fresh air from outside, or wherever you have properly set up your air pump. The loose-fitting hoods are light-weight, low-maintenance (most are equipped with disposable visor covers), and offer a wide field-of-vision. Users also say the cool outside air helps to keep their body temperatures down while they are working. Especially during the summer.

Another advantage of a supplied air system is that workers don’t need a fit test to use the hood model—and can even have a beard and wear eyeglasses. The Allegro 9821 A-750 Ambient Air Pump is the rotary vane pump which brings clean, uncontaminated air to workers operating in contaminated areas. A SAR system can only do this if it the pump is positioned in an area with clean air.

What SAR systems work best?

The A-750 pump can be used with two Allegro Constant Flow Airline Respirators or one Airline Hood Assembly.

The Allegro Economy Supplied Air Face Shield with Low Pressure Adapter provides full face protection in a hazardous (but not IDLH) atmosphere at a reasonable cost. See SAR systems below.
