Product Description

The SPEEDAIRE Air Fuse (SKU 3G-OTH-144053) is a 3/8 in NPT air fuse designed to automatically shut off airflow at a preset rate. It features a shut-off flow rate of 68 cfm at 100 psi and a cracking pressure of 4.4 psi, with an overall length of 62 mm. This device helps prevent hose whipping and air loss in the event of a downstream line rupture.

Frequently Asked Questions

What is a SPEEDAIRE Air Fuse used for?

A SPEEDAIRE Air Fuse automatically shuts off airflow when a downstream line ruptures, preventing hose whipping and air loss. It is used in compressed air systems across industrial facilities, including machining, material handling, and pneumatics departments, to improve safety and reduce waste.

What are the specifications of the SPEEDAIRE Air Fuse ?

The SPEEDAIRE Air Fuse has a 3/8 in NPT connection, a shut-off flow rate of 68 cfm at 100 psi, and a cracking pressure of 4.4 psi. Its overall length is 62 mm. These specs ensure reliable automatic shut-off in pneumatic lines to prevent hazards from line breaks.
