Exair Model 121221 1-1/4″ St. St. High Temperature Air Amplifier Kit
High Temperature Air Amplifier kits include a High Temperature Air Amplifier, shim set, filter separator and pressure regulator (with coupler) and are rated to 700°F (374°C). They are useful to circulate air in hot environments including inside ovens, furnaces and large molds. Utilizing the Coanda effect, a basic principle of fluidics, Air Amplifiers become a simple, low cost way to circulate air, move smoke, fumes and light materials. Using a small amount of compressed air as their power source, High Temperature Air Amplifiers pull in large volumes of surrounding air to produce high volume, high velocity outlet flows through a fixed air gap. They are quiet and efficient while creating output flows up to 25 times their consumption rate.
Applications
- Vent welding smoke
- Cool hot parts
- Dry wet parts
- Clean machined parts
- Distribute heat in ovens/molds
- Ventilate confined areas
- Dust collection
- Exhaust tank fumes
Advantages
Compared to Fans:
- Compact, lightweight, portable
- No electricity
- No moving parts – no maintenance
- Ends are easily ducted
- Instant on/off
- Variable force and flow
- No RF interference
Compared to Venturies and Ejectors:
- More air with lower compressed air consumption
- Higher flow amplification
- No internal obstructions
- Meets OSHA pressure and noise requirements
- Quiet
