Key Features

This family of powerful diaphragm air pumps has a cast aluminium housing (plastic on the 50 ECO) to ensure long life and silent operation. The output of the Mistral 300 is adjustable with a slide control which alters the magnetic circuit. All units have integrated replaceable air filters and are of low maintenance design. They are ideally suited to supplying air lift filters (under-gravel and box), air stones and protein skimmers using either ceramic or wooden air diffusers.
