Unlike a cold air inflatable that requires electricity to a blower the entire time the arch is in use… These airtight sealed archways only need a power source for the air pump during the initial inflation. Once inflated you close the valve, and the archway does not need a blower or air pump during use. To deflate you use the same pump that inflated it to deflate it. Inflate in 10-15 minutes.
