Performance & Efficiency

By absorbing pressure spikes and regulating the flow, this tank significantly improves the user experience and the longevity of your hardware.

• Extends Pump Life: Reduces the number of on/off cycles (cycling), which keeps the pump motor cool and prevents premature wear on the pressure switch.

• Smooth Water Delivery: Eliminates the "pulsating" or "chattering" effect at the faucet, providing a consistent stream even at low flow rates.

• Saves Battery Power: Because the pump runs less frequently, you consume less amperage, which is critical for off-grid camping or boating.

• Quiet Operation: The internal butyl rubber diaphragm dampens the vibration and noise traditionally associated with high-pressure water pumps.

Installation & Versatility

• Flexible Mounting: This unit is non-directional, meaning it can be mounted in any position. It features two 1/2" NPSM-Male ports; you can plumb it "in-line" or cap one side to use it as a "tee" installation.

• Pre-Charged Design: Typically comes pre-charged at 30 PSI, but features a standard tire-style air valve so you can adjust the pressure to match your specific pump's "turn-on" setting.

• Durable Materials: Constructed with a high-strength nylon housing and a specialized diaphragm that maintains its air charge for years without leaking.

Technical Specifications

• Total Volume: 24 oz [710 ml]

• Max Working Pressure: 125 PSI [8.8 BAR]

• Pre-Charge Pressure: 30 PSI [2.1 BAR] (Adjustable)

• Dimensions: 9.1" x 4.8" x 3.8"

• Port Size: 1/2"-14 NPSM-Male

• Certifications: NSF Listed

Maintenance Tip: For the best performance, check the tank's air pressure once per season with a standard tire gauge. The pressure should be set to 2 PSI below your water pump's "cut-in" (start) pressure while the system is unpressurized.
