Are EXAIR Air Nozzles OSHA safe?

Yes, our Air Nozzles are engineered to maintain OSHA dead end pressure standard 29 CFR 1910.242(b) and noise level exposure standard 29 CFR 1910.95(a).

Are EXAIR’s Air Guns OSHA safe?

Yes, in combination with an EXAIR air nozzle Air Guns meet the OSHA dead end pressure standard 29 CFR 1910.242(b) and noise level exposure standard 29 CFR 1910.95(a). Our guns will produce full pressure at the nozzle to maximize force and velocity of the air.

Are your blowoff products OSHA approved?

Although OSHA is not an approval agency, EXAIR products do meet OSHA noise and pressure requirements.

At what pressure should I operate the Super Air Wipe?

The maximum pressure of the Super Air Wipe is 250 PSIG. We recommend using the lowest pressure possible for the application. Always use a pressure regulator on the compressed air supply and increase pressure to the point where the application problem is solved.

Can I "T" off the hose from the Chip Vac so that I can service two machines?

The Chip Vac was designed for best performance with one vacuum hose. EXAIR has other products that may be better suited for your application.

Can I buy a Chip Vac with a longer hose?

Yes, the Chip Vac can be purchased with a longer hose. Standard vacuum hoses can be purchased in 10’ and 20’ lengths. Other custom lengths of PVC hose are available by special order. Note: Chip Vac is designed for use with a 10’ hose. Longer hose lengths may affect performance depending upon the application.

Can I buy a Reversible Drum Vac with a longer hose?

Yes, the Reversible Drum Vac can be purchased with a longer hose. Standard vacuum hoses can be purchased in 10' and 20' lengths. Other custom lengths of PVC hose are available by special order. Note: The Reversible Drum Vac is designed for use with a 10' hose. Longer hose lengths may affect performance depending upon the application.

Can I change the nozzles on the Safety Air Guns?

The nozzles can be changed on the Safety Air Guns but adapters may be required for proper fit. Contact an Application Engineer for details.

Can I connect the output of a Vortex Tube to an Air Amplifier or Air Knife?

No, for proper operation, the Vortex Tube cold outlet should not be subjected to any restrictions that would produce backpressure in excess of 5 PSIG. The hot end exhaust can withstand pressure up to 30 PSIG (depending on the cold fraction). If backpressure exceeds 5 PSIG, then the performance of the Vortex Tube will deteriorate. The hot end exhaust can withstand pressure up  to 30 PSIG (depending on the cold fraction).

An Air Amplifier or Air Knife would restrict the flow of a Vortex Tube to the point where the backpressure is excessive and severely limit the cooling capacity of the Vortex Tube.

If the goal were chilled airflow coming from an Air Amplifier or Air Knife, it would be unrealistic to expect a temperature decrease in the total output flow of either device with chilled compressed air.  Compressed air will make up a small fraction of the total airflow output from these devices. The net temperature out will be a mix of compressed and ambient air with ambient air the majority of the volume. The net effect is that the airflow is going to be the same or very close to ambient temperature surrounding an Air Amplifier or Air Knife.
