Dual Diaphragm AIR Pump 320 GPH

The General Hydroponics Dual Diaphragm Air Pump is the only air pump in the world manufactured exclusively for hydroponics systems. Ultra-quiet operation and high output make it the go-to choice for powering multiple grow systems or oxygenating reservoirs with air stones.

• 320 GPH (20 L/min) at 3 PSI — high output for demanding hydro setups
• 4 adjustable 1/4" outputs — tee off to power up to 12 air-driven systems
• Reservoir oxygenation — reliably drives air stones for dissolved oxygen
• Ultra-quiet operation — designed for low-noise grow room environments
• Hydroponics-exclusive design — engineered specifically for hydro applications, not repurposed aquarium hardware
