20 PCS 120mm Black PVC PC Fan Dust Filter Cleanable filter Antminer S9, L3,

Description

This listing is for 20 flexible, cuttable, cleanable, perforated PVC dust filters that fit all Bitmain Antminers, any model.
These filters will make the units run warmer, any filter will, our foam filters less so. If your unit can not be comfortably run a little warmer you may not want to use them, at least not before cleaning the unit completely first if it is not a new unit.
These PVC screens measure 4 11/16" x 4 11/16"  or 120 mm x 120 mm. To be used on outside of intake fan on miner.
These can be mounted using the 4 screws on the fan housing. OR, they can be held in place with a small piece of tape. Once the miner is on the suction will hold it tightly in place.  The dust will accumulate on the screen instead of going through your Antminer. Without a dust screen dust can eventually coat the surface of the heatsinks on the chips on the hashboards and cause overheating, eventually to the point of causing machines to reboot or stop hashing. Using the screen you can simply wipe it off with a damp cloth, no need to stop your miner.  This eliminates the need to disassemble
your miner to remove built up dust. Taking a miner apart you run the risk of static discharge killing a hashboard or motherboard.
You should always be grounded if taking a miner apart.
