Greenheck’s line of industrial control dampers has expanded with two 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 that control airflow and provide shutoff in lab exhaust systems.
The HCD-130LE has pressure velocity capabilities up to 8.5 in wg and 4000 fpm, while the HCD-230LE has capabilities up to 15 in wg and up to 5000 fpm. Available with parallel or opposed blade action. Can be selected as replacements for existing lab exhaust units or as a new standalone damper in custom lab exhaust units.
