Side channel blower type TD
Two impellers, two-stage – up to 1,046 m³/h
Type TD combines both: two impellers and two stages. It delivers high pressures and vacuum levels with larger air volumes than type MD.
With up to 600 mbar pressure, 450 mbar vacuum and more than 1,000 m³/h, it is the most powerful series for demanding applications.
Flow rate
up to 1,046 m³/h
Pressure
up to 600 mbar
Vacuum
up to 450 mbar
Motor power
2.2 to 22 kW
Why type TD?
Where a lot of air has to be moved against high resistance, a single-stage blower is not enough and an MD is too small. Type TD closes this gap with a single machine.
Sizes e07 to e12 belong to the EVO generation with the Smartwave™ impeller.
- Oil-free: the air only comes into contact with the impeller, not with lubricants
- Direct drive: the impeller sits on the motor shaft, without belts or gearbox
- Non-contact and low-wear: apart from the bearings, there are no parts that wear
- Built for continuous operation: IE3 motors, IP55 protection, insulation class F
- Pressure or vacuum with the same machine
- Light, robust die-cast aluminium housing
Typical applications
Pneumatic conveying
Conveying bulk materials over long lines with high pressure loss.
Large vacuum systems
Central vacuum supply for several machines or clamping tables.
Biogas and process gas
Compression of gases, also available in an ATEX version.
Deep aeration
Aeration of deep tanks with a high air demand.

Values at 50 Hz according to the FPZ catalogue. The motor power depends on the operating point; at 60 Hz, flow rate and power are higher. We will be happy to size the right model for your operating point.
Frequently asked questions
What is the difference between type TD and type MD?
Both are two-stage and reach high pressures. Type TD has two impellers and delivers roughly twice as much air as an MD of the same size.
Can the same blower generate pressure and vacuum?
Yes. A side channel blower blows on the pressure side and sucks on the suction side. Whether you use it as a blower or a vacuum generator depends only on which side you connect. The achievable values differ; see the table.
Do the values also apply at 60 Hz or with a frequency inverter?
The table shows the values at 50 Hz. At 60 Hz or with a frequency inverter, flow rate and power increase; this also allows the blower to be controlled precisely to demand. The 60 Hz values are in the catalogue.
Which accessories do I need?
At least an inlet filter and a pressure or vacuum relief valve that protects the blower against overload. Depending on the system, silencers, a check valve, a pressure gauge and an acoustic enclosure are added. Everything fits together and comes from a single source – us; see Accessories.
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.

Which blower suits your application?
Flow rate, pressure or vacuum, the conveyed medium and the operating times determine which series and size are right. We size the blower with you, supply the matching accessories and take care of installation and service.
