Newport Corp. has introduced a compact, ultraquiet air compressor that is clean, portable and more convenient than bottled air supplies. Fast-filling, the ACWS can supply air to any of the company’s pneumatic isolators, optical table systems and workstations. It operates intermittently, based on air usage, and is monitored by a sensor that maintains the reserve tank’s preset minimum pressure. It produces 30 dB at 1 ft and delivers vertical adjustment down to better than ±0.25 mm. Release valve sound level is 62 dB, and tank capacity is 1 liter. Standard features include an automatic turn-off switch, a safety valve, gauges, an outlet port, fittings, a drain and a 5-μm air intake filter/regulator that removes contaminants from the air and guarantees maintenance-free operation.
