Greenheck has expanded its line of industrial control dampers with two new models specifically designed for lab exhaust systems. Models HCD-130LE and HCD-230LE are heavy-duty flanged-style frame industrial control dampers with fabricated airfoil blades designed to control airflow and provide shutoff in lab exhaust systems. The HCD-130LE has pressure velocity capabilities up to 8.5 in. wg (2.1 kPa) and 4000 fpm (20.3 m/s). The HCD-230LE has pressure velocity capabilities up to 15 in. wg (3.7 kPa) and up to 5000 fpm (25.4 m/s). Available with parallel or opposed blade action, these dampers can also be selected as replacements for existing lab exhaust units or as a new stand-alone damper in custom lab exhaust units.
Greenheck, the worldwide leader in manufacturing and distributing air movement, control and conditioning equipment, offers the most UL certified dampers and the largest selection of AMCA licensed dampers in the industry.
