Description

The A-4000 Series Oil Removal and Pressure-Reducing Stations are available in single or dual PRV models in 10 or 20 scfm (4.7 or 9.4 l/s) maximum flow capacities. In addition, each unit features a four-way bypass valve, coalescing and activated charcoal oil removing filters, and is completely piped with copper tubing, which reduces friction, allows higher flow rates, and meets fire codes in mechanical equipment rooms. The filter combination removes oil aerosols and vapors to provide clean, oil-free air for pneumatic control systems. All models provide maximum performance for a period of 1 year, at which time the coalescing and activated charcoal filter elements need to be replaced. Gauges are provided to monitor system operations and performance. All models can provide filtered, high-pressure air to remote PRV stations. All models have a maximum input pressure rating of 150 psig (1,050 kPa) and an upper temperature limit of 125°F (52°C).
