Description
The Crandall 21-38-CSS Tubing Flow Restrictor 1.0 SCFH is a pneumatic control component designed to limit air flow through control tubing in HVAC systems. This restrictor provides a calibrated 1.0 SCFH orifice that helps regulate pneumatic signal speed and pressure changes within control circuits. Engineered to Crandall specifications, it supports stable and repeatable airflow control, reducing overshoot and oscillation in pneumatic actuators. Ideal for HVAC technicians and controls contractors, it helps maintain predictable system response and improve the performance of pneumatic logic and control loops.
