Hi, I’m looking for an air pump that can be programmed to infate for 5 seconds, hold at a certain achieved pressure for 5 seconds and then deflate again, after which the cycle starts again. This is for an inflatable massage cushion so it doesn’t need much power, not much air pressure. Does anyone know of any air pump that can be controlled to cycle between inflating and deflating like that, perhaps controlled electronically? Thanks in advance!
