Air blower 1½" 400VAC type 040 single impeller 1.3kW - 7042253

Air blower 1½” 400VAC type 040 single impeller 1.3kW

Rated at 1.3 kW and delivering a maximum airflow of 145 m³/h through a 1½” (DN40) outlet, this three-phase 400 VAC single-impeller air blower is sized for commercial and semi-commercial pool and spa installations where a robust, continuous-duty air supply is required. The type 040 designation refers to the impeller housing diameter, placing this unit in the mid-to-large range of inline blowers commonly used to power air-nozzle benches, bottom-massage grids, and whirlpool jet systems.

Airflow & continuous operation

With a rated capacity of 145 m³/h, this blower can feed extensive nozzle arrays in large in-ground spas, hydrotherapy pools, and public wellness installations. The single-impeller design delivers a clean, direct airflow path that keeps internal resistance low and supports sustained duty cycles without thermal overload — an important consideration in commercial environments where the blower may run for extended periods across multiple sessions per day.

Electrical supply & installation

The 400 VAC three-phase supply requirement makes this unit a professional-grade component, suited to plant rooms and equipment bays that already carry an industrial electrical feed. Installation must be carried out by a qualified electrician. As with all pool air blowers, the unit must be positioned above the water line or plumbed with an anti-siphon loop on the connecting pipe to prevent water from backing up into the motor.

Connection & pipework

The 1½” (38 mm) pipe connection is a widely used diameter in European pool and spa pipework, allowing straightforward integration with standard PVC or ABS push-fit and solvent-weld fittings. The outlet accepts common pool-grade couplings, so the blower can be dropped into an existing installation or incorporated into a new equipment room layout without bespoke adapters.
