The CPPC Purge Connector for SM1 Lens Tubes makes enclosed SM1 lens tube systems compatible with our PACU Pure Air Filtration System via the hose barb. The barb is compatible with 3/16" internal diameter tubing, such as that included with the PACU system or the tubing sold below. The purge connector has SM1 (1.035"-40) internal thread to use with SM1 Lens Tubes or accessories. It also features four Ø6 mm bores for compatibility with our 30 mm cage system and is 0.75" (19 mm) thick. Each cage locking set screw has a 5/64" (2 mm) hex. The bottom and side of the cage plate also offer 8-32 (M4) mounting holes for post mounting.
We recommend using two or more CPPC Purge Connectors with our pure air filtration system, which has two connections: one for supply and one for return. The device incorporates dessicant and particulate filters in series and excels at providing an extremely clean, dry atmosphere for closed-loop experimental setups.
Note: The CPPC Purge Connector is strictly intended for purging or purifying the air in a lens-tube-enclosed beam path. Our lens tubes are not air tight and the SM1 thread is not suitable for pressurized or vacuum applications. Please do not apply sealant or tape to the thread.
