The device has two controls, automatic and manual. When filtering, the water flow is top-down and filtered through the water distributor, filter material layer and water collector.

Small vacuum pump, how to choose? 1. start the problem with load.If the micro-air pump already has a vacuum or a exhaust port before starting, consider another technical parameter of the pump: The maximum starting load Pis value of the air inlet, maximum starting load Pos value for exhaust port. A typical application case is to use a micro-gas pump to maintain a vacuum or positive pressure state in the container. when the vacuum or positive pressure in the container is lower than the set value, the pump needs to be electrically started and stopped when it is higher than the set value. The products that can be started under the limit vacuum degree that they can achieve are: VM series, VAA series, PK series, PC series, VCA series, VCC series, VCH Series, VBH series; the products that can be started under the maximum output pressure that they can achieve are: FM series, FAA series, and PCF series. This performance has higher requirements for the manufacturer's technical level.2. medium temperature proble
