Sweetwater® Linear II Diaphragm Air Pumps, Outdoor, 180" max depth, 8" x 5" x 9", 90 running watts
With higher output and lower watts—our best linear air pumps.
Sweetwater® Linear II air pumps average about 40% more air and about 20% lower power consumption.
You will see similar looking linear air pumps imported from Asia, but the Sweetwater® brand is significantly different. These Sweetwater® air pumps are designed for 60-Hz (American) operation to produce maximum efficiency (we also offer 50-Hz models for export). These models permit continuous operation exceeding 3 years! Simply clean the air inlet filter as needed. There is no need for lubrication, and the outlet air is always clean.
Besides being efficient, Sweetwater® linear air pumps are quiet. You can even operate them right in the classroom, pet store or laboratory. Each uses a heavy, cast-aluminum, dripproof housing.
Standard models are 115V/60 Hz with 6' power cords. UL-listed and CE-approved. Three-year warranty (does not include filters or diaphragm). 230V/50 Hz export models are available and have the same wattage as 115V/60 Hz units.
SL94A has a 90-watt reset safety switch.
