450W Inflatable Air Blower

What is in the box: the 450W Inflatable Air Blower, its power cord, the user manual and two ground stakes. The inflatable, extension cord and electrical outlet are not included.

Airflow and matching the inflatable

The listed airflow is 450 m3/h through 4.1 in / 10.5 cm. The right starting point is the inflatable’s own tube and recommended blower size, not the blower’s wattage alone. A loose tube leaks air even when the motor is powerful, while a restrictive or undersized tube can make a larger blower work harder without keeping the inflatable firm.

The unit runs on 450 W, 110-120 V AC, 60 Hz, 4.2 A and uses 0.6 HP. Keep the intake and outlet clear and do not use it for sealed inflatables that need a trapped high pressure.

Setup for a bounce house or slide

A bounce house or slide only holds its shape while the blower keeps supplying air. Match the outlet to the tube, tie the tube securely and keep the blower on firm ground while people are using the inflatable. Check the intake, cord and connection before every session, and stop using the inflatable if the blower moves or the tube comes loose.

Set the blower on level, firm ground with the outlet pointing toward the inflatable tube.
Keep the intake away from grass, loose fabric and standing water.
Fit the tube over the outlet and close the drawstring or fastener shown in the inflatable manual.
Connect the power at a dry, GFCI-protected outlet and keep the cord out of walkways.

Power and weather

The 450 W model has no published IP water-resistance rating. Keep the blower, plug and switch out of rain and puddles even when the inflatable itself is a water slide. The unit runs on 450 W, 110-120 V AC, 60 Hz, 4.2 A; use a grounded circuit rated for the load and do not daisy-chain extension cords. If the housing or plug gets wet, stop and unplug it before handling.

Portability and storage

The blower weighs 7.7 lb / 3.5 kg and measures 13.8 x 8.5 x 14.6 in / 35 x 21.5 x 37 cm. Let it cool after use, wipe off dust, inspect the intake and outlet, and coil the cord without bending the plug. Store it dry with the vents clear.

Wholesale pricing

One unit, wholesale pricing. The listed price is the wholesale rate for one blower. There is no minimum order quantity and no separate tier price, so buying one unit and buying several units use the same listed unit price.

Frequently Asked Questions

Q: What kind of inflatables can it run?

A: It is intended for continuous-flow inflatables such as bounce houses, water slides, obstacle courses and similar open-air products. It is not designed to inflate sealed tires, air mattresses or airtight bags.

Q: What is the outlet diameter?

A: The outlet measures 4.1 in / 10.5 cm. Check the diameter of the inflatable tube and use the drawstring or fastening method supplied with the inflatable to hold the tube around the outlet.

Q: How much air does it move?

A: The listed air volume is 450 m3/h. For a small or medium inflatable, lower-volume airflow is often enough; a large commercial inflatable may need a higher-output model rather than a tighter connection alone.

Q: Does the blower need to run the whole time?

A: Yes. A continuous-flow inflatable needs air while it is in use. Keep the intake clear, check the outlet connection and make sure the blower cannot tip or slide while the children are playing.

Q: Can I use it outdoors?

A: Yes, it is made for outdoor inflatables, but the switch, plug and socket must stay dry. Place it on firm ground under stable weather, keep cords out of standing water and use a GFCI-protected outlet.

Q: Is it waterproof?

A: No IP water-resistance rating is published for this model. The covered switch is not a substitute for keeping the blower and electrical connection out of rain or standing water. Stop and unplug it if the housing or plug gets wet.

Q: How loud is it?

A: The listed noise level is about 60 dB. Noise can rise with the surface it sits on and how the outlet is loaded, so place it away from seating areas and keep the vents unobstructed.

Q: Why does the selector say 480W when the page says 450W?

A: The selector labels this variant 480W, while the motor specification table and gallery rate it at 450W / 0.6 HP. Use the 450W figure for circuit planning and treat 480W as the variant name shown on the page.

Q: Can I use an extension cord?

A: Use only a grounded outdoor extension cord rated for the blower current and keep the connection dry. Do not coil a live cord under the inflatable or run it through a puddle.

Q: How should I store it?

A: Let the housing cool, wipe off dirt, check the intake guards and coil the cord without bending the plug. Store it dry and keep the outlet and vents clear of dust and debris.
