Steelhead Composites MicroMax series lightweight 3,000 psi (207 bar) bladder accumulators come in 1.0 gallon (4 liter) and 1.3 gallons (5 liter) capacities. These small and lightweight composite accumulators are a superior alternative to steel accumulators for any weight-restricted uses, mobile and industrial applications where access is remote, elevated or limited.
These bottom repairable bladder accumulators are Aluminum lined composite pressure vessels consisting of a fluid port on one end and a gas port on the other. The large opening in the fluid port allows easy maintenance and replacement of the rubber bladder. The bladder is pre-charged with Nitrogen gas before the accumulator is put in to hydraulic service. A poppet valve in the fluid port prevents extrusion of the pre-charged bladder. A valve on the gas port allows periodic re-charging of the Nitrogen gas.
