LX AP400 V2 Hot Tub Air Blower

LX AP400 V2 Hot Tub Air Blower

This LX AP400 V2 Hot Tub Air Blower - AP400-V2 is designed specifically for use with hot tubs and spas. It is a 400W air blower with LX's V2 double impeller design, built to provide steady airflow for bubble systems on medium to larger spa installations. Commonly used on a range of portable spas and whirlpool systems, it is also found on brands such as Danz, Spa Serve, AMC Winer, Cascade, MAAX, Monalisa and Trinity.

Key Features

• The V2 double impeller motor is designed to give strong, even airflow with lower high-pitched noise than older single impeller styles.
• With output suitable for around 12 to 24 air jets, it is a practical choice for medium to large hot tubs and spa seats with multi-jet bubble systems.
• The blower uses a 1" threaded air outlet connection, typically measuring around 32-33mm across the outside of the union.
• Electrical connection is via a 1.5m cable fitted with an AMP-style plug, making it a straightforward replacement where the same lead type is already in place.
• The angled mounting bracket allows the unit to be fitted upright or on its side, depending on the cabinet layout.
• The reinforced heat-resistant ABS housing is intended for spa cabinet conditions where reliability and resistance to heat build-up matter.
• It is commonly used with Aeware in.ye and Balboa control systems where the plug and pin configuration match.
• The AP400-V2 is backward compatible with earlier AP400 versions and is often used as a direct replacement on many Chinese-built portable spas.

Fitting Guide

If replacing a like-for-like LX AP400 V2 Hot Tub Air Blower or AP400-V2, installation is usually straightforward. Isolate power to the spa first, remove the blower power cable from the spa control box, unthread the air outlet pipe connection, remove the fixings holding the blower in place, then fit the new unit in reverse order. Check that the replacement voltage, plug type and union size match the existing blower before reconnecting.

For new installations, this blower is intended for portable spa use and is normally mounted inside the spa cabinet within 2 metres of the spa, with enough surrounding airflow for cooling. The bracket allows upright or side mounting to suit the available space. It uses a 1" threaded outlet and a 1.5m AMP-style lead, and is commonly paired with Aeware in.ye and Balboa systems where the connector matches. If the original blower failed due to water ingress, inspect the air line one-way valve before fitting the replacement.
