EH Series – Standard Series

The Max-Air EH Series electro-hydraulic actuator is the standard and highly customizable solution for self-contained fail-safe electro-hydraulic ESD applications. In addition, the EH Series provides a robust and cost-effective platform for on/off, modulating, double-acting, spring-return, and any combination of operational requirements, including modulating double-acting fail-in-place control. Precisely manufactured for ordinary (NEMA 4,4X and IP65) and explosion proof (Class 1 Div 2, NEMA 4, 4X, 7, 9, IP67) environments, these units are a dependable solution and an excellent cost effective alternative to fail-safe electric actuators.

EHD – Heavy Duty Series

The Max-Air EHD Heavy Duty Series electro-hydraulic actuators are built upon the Max-Air SHD/CHD Scotch Yoke platform for even higher torque applications, up to 2,738,990 in-lbs (228,250 ft-lbs). Available in standard configuration for easy customization (utilizing an appropriate electrical enclosure and desired electronics), or available with the same circuit board technology of the EHS Slimline Series in order to keep the overall envelope size as small as possible.
