VEVOR Inflatable Paint Booth, 21 x 13.5 x 9.8 ft Inflatable Spray Booth, with 1100W Powerful Blower and Air Filter System, Large Furniture Painting, Portable Car Paint Booth for Medium-Sized Vehicles

The product has only one air outlet and cannot be equipped with another blower. I recommend one model that are equipped with two blowers:https://www.vevor.com/inflatable-paint-booth-c_10313/vevor-inflatable-paint-booth-23-x-13-1-x-9-ft-inflatable-spray-booth-with-750w-480w-powerful-blowers-and-air-filter-system-portable-car-paint-booth-for-small-truck-large-motorcycle-midsize-suv-p_010696680503

There is enough room to paint.

No,we can't make custom sizes.

The floor is made of Oxford cloth material. As long as the floor is not suspended, there is no problem with load-bearing. Please be careful to avoid sharp objects from scratching the floor.

It will stay up for 30 seconds if the blower is off.
