LX AP900 V2 Hot Tub Air Blower

LX AP900 V2 Hot Tub Air Blower

The LX AP900 V2 Hot Tub Air Blower - AP900-V2 is designed specifically for use with hot tubs and spas. This 900W air blower is a high-output unit for larger installations, commonly fitted to swim spas, large domestic hot tubs and spa systems with bigger air jet layouts. It uses LX's double impeller V2 design to produce strong airflow with quieter running than many single-stage blowers, and is often found on spas from brands such as Danz Spas, Spa Serve, AMC Winer, Cascade, MAAX, Monalisa and Trinity.

Key Features

• The 900W motor provides strong air output for larger hot tubs, swim spas and systems with around 20 to 40 air jets.
• LX V2 double impeller construction helps deliver consistent airflow with a softer air delivery and noise levels below 74 dB(A).
• The blower uses a standard 1" threaded union connection, with an outlet size of approximately 32-33mm OD and outlet diameters of 40mm internal and 47mm external.
• A 1.5 metre cable is fitted, typically with an AMP-style plug or ring terminal arrangement depending on version, with Mini J&J adapter options available if required.
• An integrated pneumatic switch connection allows use with a pneumatic air button where the spa setup supports it.
• The angled mounting bracket allows the unit to be installed upright or on its side to suit cabinet space.
• The reinforced heat-resistant ABS housing is built for spa cabinet conditions and pairs with Class F motor insulation and thermal protection.
• AP900-V2 is backward compatible with earlier AP900 versions, making it a practical like-for-like replacement in many existing LX blower setups.
• This model is regularly used on larger Chinese-built spa systems and is particularly suited to swim spas or larger hot tubs needing higher air volume.

Fitting Guide

If replacing a like-for-like LX AP900 V2 Hot Tub Air Blower or AP900-V2, installation is usually straightforward. Switch off power to the spa completely, remove the blower power cable from the spa control box, unthread the air outlet pipe connection, remove the fixings securing the blower in place, then fit the replacement in reverse order. Before connecting power, check that the supply voltage matches your existing system and confirm the plug or terminal layout matches the spa pack.

For new installations, this blower should be mounted in a dry, ventilated position with enough room around it for cooling and future servicing. The unit can be mounted upright or on its side using the angled bracket. It connects to a 1" threaded union and may also be used with a pneumatic control connection if required. On spas with long air lines or where a previous blower has failed through water ingress, it is worth checking the air line non-return valve is operating correctly before fitting the new blower.
