Newstripe Safe2Vent™ Complete Filter Assembly, 10004701

Safe2Vent coalescing carbon filter with the exclusive Viz-a-Ball indicator fits any 3/4" bung fitting and is designed for use with any single aerosol can manual puncturing unit. The indicator tells you when the process is complete and it is safe to open the puncturing machine. The check ball 'closes' the drum when not processing for compliance with EPA and California regulations while allowing venting of any dangerous pressures to conform to OSHA guidelines. Designed for use with 30 gal or 55 gal drums.
