👍【Super Powerful】What we emphasize too much is that unlike the compressed air can, this electric air duster is much more powerful in dusting off the keyboard, computer, laptop, window gap, or dust in any crevice and hard to reach places. Up to 37000RPM rotating speed plus 500 watt make this air blower become your best choice. | 👍【Adjustable Speeds】To satisfy different air power needs, this air duster are adjustable in two speeds, the high speed can blowing away the stubborn dust like those stuck in the gliding door rail and the low speed can removing the dust on the desk, computer, keyboard. | 👍【Multiple Use】To further meet your different dust removing and inflating needs, we have thoughtfully equipped this air blower with 4 different nozzles. By changing different nozzles, you can not only clean the computer host, keyboard, air conditioner, sofa etc with this air duster, but also inflate the swimming ring, the toy pool and airbed as you wish. | 👍【Safe and Durable】The dust blower is made of flame-retardant materials, which is safe. Sturdy and thick enough housing case indicate an obvious fact that it’s durable for years of use. The sponge net at the bottom of the air inlet can be cleaned, replaced and reused, further prolonging its lifespan and reduce the noise when it is working. | 👍【Handy and Convenient】This electric air duster have a decently sized 9.84FT cord and unique ergonomic design which makes it reasonable being handheld and easy being maneuvered. (WARNING: When using the air duster, please lift it up and don’t let its bottom be placed on the ground to work directly or block airflow either incoming at bottom otherwise it will damage the machine.)
