Frequently Asked Questions

What is the difference between a side channel blower and a centrifugal blower?

Side channel blowers generate vacuum and pressure through a regenerative principle, ideal for high vacuum/pressure with moderate flow. Centrifugal blowers use impeller rotation for higher airflow at lower pressure, suitable for ventilation and aeration.

Are your blowers oil-free?

Yes, our side channel and centrifugal blowers are oil-free, ensuring clean air output for sensitive applications like food processing, pharmaceuticals, and wastewater treatment.

Do you offer ATEX-certified explosion-proof blowers?

Yes, we manufacture ATEX-certified explosion-proof blowers suitable for hazardous environments with flammable gases or dust.

Can you customize air knife lengths?

Yes, we provide custom-length air knives in stainless steel or aluminum to fit your production line requirements.

What is the warranty on your products?

We offer a standard 12-month warranty on all blowers and pumps, covering manufacturing defects and material failures.
