Horizontal Airlanco Series HE (High-Efficiency) serves as primary receiver in dilute phase pneumatic conveying systems, separating hot, cold, moist, and large particles that can plug or damage filter receivers. Cyclone has no filter media to maintain; dust particles are forced against walls and separated from air stream by inertia and gravity. Internal riser tube directs secondary vortex created by internal airflow to rotatable draw-thru discharge opening. Cyclone comes in durable carbon or sanitary stainless steel, with round or square inlets; heavy-duty support structure simplifies installation and ensures safe, stable operation.
