(12) The Heavy-Duty (HD) Aerolock™ is engineered for heavy duty industrial service and high volumetric efficiency at up to 1.0 bar [15 PSI] pressure differential and temperatures up to 107.2°C [225°F]. When used in a conveying system, the pressure differential limit is 0.8 bar [12 PSI].
The HD has an eight-blade rotor that maintains a minimum two-blade labyrinth seal to minimize air leakage. The eight-blade rotor is available with flat or relieved tips in several rotor choices. The HD utilizes a single radial ball bearing on the drive side and two tapered roller bearings on the thrust side.
Standard Mechanical Specifications:
Round or square inlet/outlet flange patterns
Cast iron or stainless steel housing; stainless ...
(24) The Maximum-Duty (MD) Aerolock™ is commonly used with some of the most challenging materials including minerals, chemicals, fillers, food ingredients, filled pellets, PVC compound and diatomaceous earth. The MD is engineered for heavy to severe industrial service with pressure differentials up to 1.4 bar [20 PSI] and/or temperatures of 121°C [+250°F]. The ability to withstand severe shock loads and elevated temperatures make the MD Aerolock a "true maximum duty" performer.
The MD has a ten-blade, rotor that maintains a minimum three-blade labyrinth seal to minimize air leakage. The ten-blade rotor is available with flat or relieved tips in several rotor choices. The MD utilizes two tapered roller bearings on both the thrust and ...
(6) The Quick-Clean (QC) Aerolock™ is well suited for use in the food, chemical, plastic, and pharmaceutical industries where contamination is a constant concern and frequent disassembly and cleaning is required. Without disengaging the valve from the system, the QC can be easily disassembled, cleaned, and reassembled. The optional support carriage is ideal for use in high places to facilitate rotor removal. The carriage fully supports the rotor as it is removed for cleaning.
Incorporating the same maximum-duty features as the MD Aerolock, the QC offers 24-hour service at pressure differential up to 0.8 bar [12 PSI]. The QC has a ten-blade, rotor that maintains a minimum three-blade labyrinth seal to minimize air leakage. The QC ...
(6) The Blow-Through (BT) Aerolock™ configuration enhances rotor cleanout and makes installation in tight quarters possible. It is often used in sticky material applications to prevent material build-up in the rotor pockets.
The BT is designed for heavy-duty industrial service in applications of up to 0.8 bar [12 PSI] pressure differential. Eight blades maintain a minimum two-blade labyrinth seal to minimize air leakage. The rotors are equipped with relieved tips for materials that form skins or thin sheets on end plates and housing, or non-relieved tips for cereal products. The BT utilizes a single radial ball bearing on the drive side and two tapered roller bearings on the thrust side.
(12) The Light-Duty (LD) Aerolock™ provides an excellent seal in low pressure or low vacuum service. It is ideally suited to continuously discharge from cyclone or filter-type dust collectors where a head of material does not build up on top of the Aerolock inlet.
Pressure differential across the LD is limited to a maximum of 0.2 bar [3 PSI], allowing the flexible tip rotor to keep air loss to an absolute minimum. Flexible tips eliminate tolerance adjustments, and the rotors are easily replaced as they wear. They are ideal for use with fine powders and dusts commonly associated with cyclone and dust collector applications. The LD utilizes a single radial ball bearing on both the thrust and drive sides.
The Maximum-Duty (MD) 1820 Aerolock™ is Premier's largest rotary valve available and is designed for high volume service. The MD 1820 is commonly used with some of the most challenging materials including minerals, chemicals, fillers, food ingredients, filled pellets, PVC compound and diatomaceous earth. The MD 1820 is engineered for heavy to severe industrial service with pressure differentials up to 1.4 bar [20 PSI] and/or temperatures of 121ºC [250ºF]. The ability to withstand severe shock loads and elevated temperatures make the MD 1820 Aerolock a "true maximum duty" performer.
The MD 1820 has a ten-blade, rotor that maintains a minimum three-blade labyrinth seal to minimize air leakage. The ten-blade rotor is available with ...
(12) This group of Heavy-Duty and Blow-Through Rotary Valves are designed with T3 Seals for the specific purpose of conveying flour during milling processes.
