Miniature In-Line Screens and Breathers Provide Big Benefits in Particulate Control

Miniature in-line screens/breathers help engineers protect critical components from damage or reduced performance due to clogging or reduced flow rates. Designed to augment the protection of critical components in fluid control systems, the fine screens are intended to prevent the occasional particles that enter the fluid during installation or otherwise.

The primary objective for these devices is simple: a last chance to catch any solid contaminants and prevent them from entering a component or a system. This makes them ideal for use with precision orifices, pneumatic transducers, gas and liquid flow instruments, medical devices, filling and purging systems, pneumatic timers, transmitters, pneumatic transmission lines, hydraulic controls, leak test equipment and flow measurement devices. O’Keefe Controls Co.’s fine screen breathers provide an air passage into equipment, enclosures, and pneumatic controls while preventing the ingestion of solid particles. The stainless steel wire screens do not introduce loose particles into the fluid stream. The screens are thoroughly cleaned to prevent inadvertent introduction of contaminants.

Four levels of particle retention are available (10, 15, 25 and 100 microns) in either brass or 303 stainless steel housings. Miniature fine screen breathers are rated at 15, 25 or 100 microns and are available in either brass or stainless steel fittings. Connection sizes are 10-32, 1/8″ or 1/4″ NPT. In all cases, the screen material is 304 stainless steel.
