Check the listing for details. MCH6 Repackable Refillable Filter for SCUBA Diving Coltri Compressor. Condition: New. Listed at 235.57 USD. Repackable Coltri MCH6 Compressor Filter (With beta testing now complete, these are properly good to go! Includes Teflon washer to prevent scratching and SS spring inside) Using repackable filters can lower your running cost significantly. This one is designed to replace Coltri cartridges #SC000340-MHC which are used in small compressors such as the MCH6. You'll want to double check this before buying! Fully welded stainless steel construction, supplied packed and ready to go (electric motor type), this repackable cartridge is designed to outlast your compressor. There are many people around the world repacking their own filters and it's not rocket science - just requires some care and if you stuff it up you will get oily air or worse. A minor risk that needs to be accepted. A comprehensive user manual including repacking instructions is supplied with the filter. Spare felt pads and repack kits will be available - send me a message if you want some with your filter. If you need a different kind of filter (or anything similar), I can make it for you, just let me know. P21 (for small Bauer compressors) and P31 (for Bauer Mariner and the like) are usually stocked and can be found in my other listings. Pickup is welcome from Oakleigh South.
