The BP-1 air barrier is designed to protect the window shields and mirrors of the PPW-40REx against the oil vapours, sand, dust and other solid particles deposition.
PPW-40REx flame detectors are often used in heavily contaminated and dirty locations. Such conditions require the glass shields and mirrors frequent cleaning.
BP-1 air barrier is designed to protect glass and mirrors against settling of oil, sand, dust and other solid particles.
Special air stream generated by the BP-1 air barrier continuously protects the optical window of the PPW-40REx flame detector from settling dirt and contaminants.
