A2A Series

Up to 85% smaller and 45% lighter than conventional spring-return cylinders. The A2A penumatic booster has a smaller foot print resulting in less factory floor space being used.

Features:

Air driven, double acting pressure amplifiers
No mechanical or electrical power required
4:1, 3:1 and 2:1 intensification ratios
Compact, lightweight, corrosion resistant construction
High air flow output 100 cu in per stroke
Ideal to fill large air tanks where plant line pressure is low
Quiet operation
