Air Supply of the Future, Inc. blower parts for spas and whirlpool pools

Air blowers are the quiet workhorses of a whirlpool system. While the pump moves water, the blower pushes a column of warm, low-pressure air into the air channel so the jets fizz and the seats bubble. Because that air travels through damp pipework and the unit itself often sits in a cramped, humid plant space, the motor inside the blower housing tends to be the first component to give up. Here you will find replacement motors for the Ultra 9000 series, so a working blower housing does not have to be scrapped because of a failed motor.

The range currently covers two power ratings – a 1 HP motor under part code 1.0220BLR and a 2 HP motor under part code 2.0220BLR. Both are sold as service motors for the Ultra 9000 blower, which means the fan section, the housing and the mounting arrangement stay in place and only the rotating assembly is renewed.

Why blower motors fail

A spa blower runs in conditions that few electric motors enjoy. It starts and stops many times a day, it handles air that has passed close to heated water, and it is frequently mounted in a cabinet with limited ventilation. The usual failure patterns are easy to recognise:

• Bearing wear – a rising whine, a rumble or a vibration that was not there last season, often worst in the first seconds after start-up.
• Moisture ingress – water drawn back along the air line when a check valve fails or when the blower is fitted below the waterline, which corrodes the windings and the bearing races.
• Thermal cut-out tripping – the unit runs for a few minutes, stops, then restarts once it has cooled, usually a sign of a blocked air intake or a motor nearing the end of its life.
• Loss of air volume – the jets still bubble but weakly, because the motor no longer reaches full speed under load.
• No start at all – a hum without rotation, or complete silence when the blower button is pressed.

A motor that has taken on water is rarely worth drying out; replacing it is the practical repair, and it restores the original air output rather than masking the problem.

Choosing between the 1 HP and 2 HP motor

Start with the rating of the motor that is being removed, not with the size of the spa. The blower housing, impeller and air line were matched to a particular output, and fitting a larger motor does not automatically give more bubbles — it can simply load the same restricted pipework harder. Before ordering, check the following:

• The nameplate on the existing motor, which carries the horsepower rating and the electrical details; this is the single most reliable reference.
• The part code – 1.0220BLR for the 1 HP version and 2.0220BLR for the 2 HP version, so the two are easy to tell apart on an order or an invoice.
• The supply at the spa pack or control box, confirmed against the existing motor’s markings before anything is disconnected.
• The mounting and shaft interface, so the impeller and housing refit without modification.
• Cable entry and terminal arrangement, which should match the existing wiring route to avoid stretching or straining the leads.

Photograph the wiring before disconnecting it, and label the conductors. Electrical work on pool and spa equipment should be carried out by a qualified person and in line with local regulations.

Fitting and protecting the new motor

Two details do more than anything else to extend blower life. First, mount the unit above the waterline wherever the installation allows, and make sure the air line rises in a loop before it drops to the spa shell so that water cannot siphon back into the motor. Second, keep the air intake clear — dust, leaves and insulation pulled against the inlet starve the motor of cooling air and push it towards its thermal limit.

It is also worth checking the non-return valve in the air line at the same time. A tired check valve is often the hidden reason a blower motor failed in the first place, and renewing it costs far less than a second motor.

Here we list replacement motors for the Ultra 9000 blower in both the 1 HP and 2 HP ratings, identified by the codes 1.0220BLR and 2.0220BLR. They are stocked as service items for installers and spa owners who have a sound housing and simply need the drive side renewed.

If the nameplate on the old motor is unreadable, send the blower’s own markings and a photograph of the mounting face and wiring, and the correct rating can be confirmed before you order.
