High-temperature side channel blowers
For hot air and technical gases up to 350 °C
Standard side channel blowers are designed for air at ambient temperature. If hot air or hot gas has to be conveyed, for example in drying systems or when recirculating process air, a purpose-built machine is needed.
For this, FPZ builds blowers with thicker walls and a design that works reliably in continuous operation even at up to 350 °C.

Why a high-temperature blower?
Reusing hot air instead of blowing it off saves a lot of energy. For this to work, the blower must withstand the temperature permanently without warping or losing performance.
Because temperature, medium and operating point strongly influence the sizing, we configure each high-temperature blower for your application.
- For air and technical gases up to 350 °C
- Reinforced walls for extreme temperatures
- Designed for continuous operation
- Oil-free conveying, non-contact impeller
- Sizing for your operating point
Typical applications
Drying systems
Recirculating hot drying air in industrial ovens and dryers.
Heat recovery
Returning hot process air instead of blowing it off outdoors.
Thermal processes
Conveying hot gases in firing, hardening and treatment plants.
Plastics and textiles
Hot air for drying, shrinking and setting.
Frequently asked questions
From what temperature do I need a high-temperature blower?
As soon as the intake air is significantly warmer than normal ambient conditions. The exact limit depends on size and operating point. Tell us the temperature, and we will check whether a standard machine is sufficient.
Are there performance tables?
Hot air is less dense than cold air; flow rate and pressure change with temperature. That is why we always size high-temperature blowers for the specific case instead of choosing from a table.
How much maintenance does a side channel blower need?
Very little. The impeller runs without contact, and there is neither oil nor belt. The main things to check are the inlet filter and, after many operating hours, the bearings. On request, we take care of maintenance and repair for you.
Conveying hot air?
Tell us the temperature, medium, flow rate and pressure. We will size the blower with FPZ for your application.
