Single phase axial fan without plate.
Often used on generators, aircon units, heat pumps etc.

These are now an end of line item which we have good stock of, thus we are able to offer at this very competitive price. These normally retail at over £270.

B-Flow fan. (impellor over motor) so the airflow goes past the impellor then out through the grille, (see additional picture) so if you are facing the grille the airflow is towards you.

Similar to the BPN versions but with a vertical power cable outlet from the motor (BMVPN) rather than from the side.

* 6 pole motor. (Quieter but slightly less airflow than than the normal 4 pole motor)
* Airflow max: 4350 m3/hr.
* Temps: min -40°C, max +70° C
* IP54 rated so suitable for external mounting.
* Current Max: 0.6A
* Weight 8Kg

One datasheet is for a A-Flow version but all details are the same apart from the airflow direction and a slight size difference due to the different impellor shape.. The B-Flow datasheet has the correct dimensions.

Bulk purchase discounts available.
