Air Blowers (Air Knife / Air Pump)
High-speed air blowers for blow-off, drying and air-knife applications that need a concentrated air stream. Final selection is confirmed at the duty point (airflow / static pressure / voltage / control mode) and by project verification.

Air Blowers (Air Knife / Air Pump) — selection guide
Air Blowers (Air Knife / Air Pump): 40 models, frame sizes 24–49 mm, maximum airflow 600–4,800 m³/h, static pressure to 2,650 Pa, AC motors, across 0 series.
AC air blowers for blow-off, drying and air-knife duties: LWB compact blowers (Ø24–37 mm impeller, 600–850 m³/h at 800–1,900 Pa, 180–550 W) and LWT blowers (Ø43–49 mm, 850–4,800 m³/h at 1,700–2,650 Pa, 680–2,250 W) on 230 V, 120 V and 220–240 V. These are high-speed units that deliver a concentrated air stream rather than volume ventilation.
How to select from this range
- Select by the pressure at the nozzle or air knife, then check airflow; the two are traded across the curve.
- Specify 120 V for North American equipment, 230 V for Europe; both are listed.
- Plan for the sound level — high-pressure blowers are loud; remote mounting and a silencer are usual.
Where these fans are used
- Air knives and blow-off drying
- Inflatables and air mattresses
- Dust removal on production lines
- Combustion air for burners
Every figure above is measured on our own test rigs per AMCA 210 / ISO 5801 methods — see the test labs and certificates. Final selection is confirmed at the duty point and by project validation.
FAQ — Air Blowers (Air Knife / Air Pump)
What is the difference between the LWB and LWT blowers?
LWB are the compact 180–550 W units to 1,900 Pa; LWT are the 680–2,250 W units to 2,650 Pa and 4,800 m³/h for air knives and larger drying duties.
