Materials & Construction Options
Housing & Anti-Spark Inlet Design
Copper / Brass Spark-Resistant Lining: Non-ferrous copper or brass inlet cone paired with steel impellers to prevent mechanical ignition sparks during potential wheel-to-inlet contact.
Cast Aluminum Alloy Casing: Light-weight, spark-free A356 aluminum alloy housings for portable and compact wall-mounted axial units.
Conductive Resin & Synthetics: Anti-static conductive FRP and polypropylene containing embedded carbon black, maintaining surface electrical resistance under 10^9 Ohms to dissipate electrostatic charge.
Heavy-Gage Carbon Steel / Stainless Steel: Continuously welded 304 or 316L stainless steel casings passivated for combined explosive and corrosive atmospheres.
Impeller & Shaft Grounding
Die-Cast Aluminum Impellers: Precision-balanced spark-resistant aluminum wheels engineered for high rotational stability and low inertia.
Shaft Grounding & Bonding: Copper grounding straps and conductive shaft brushes providing continuous electrical grounding between rotating parts, frame, and earth terminal.
Dynamic Balance Precision: Impellers dynamically balanced to ISO 1940 Grade G2.5 standards to prevent vibration-induced contact within the casing inlet cone.
