Features:
P84 Felt filter Media provide a unique and cost effective solution for many tough industrial
baghouse applications. Versatile and efficient,P84 usage ranges from minerals processing, low acid coal fired boilers, asphalt/hot mix plants, to soil remediation facilities.P84 fibers are needled into filtration quality felts to be sewn into filter bags suitable for use in pulse jet style baghouses. The unique tri-lobal fiber structure of P84 provides customers with high efficiency filtration, low pressure drop, and reduced cleaning energy.
