Rotary Airlock

Rotary valve, rotary airlock, and rotary feeder solutions for sealed, controlled material discharge at filter, cyclone, silo, and hopper outlets. Hantech Filter evaluates material properties, target capacity, line geometry, drive, wear, sealing, and maintenance access together within the same transport system.

Controlled dosing with rotary feeder / airlock

False-air (air infiltration) checks under the filter and cyclone

Standard, heavy-duty, and stainless steel housing options

Motor-gearbox, speed, rotor, and cell volume selection

Capacity, wear, jamming, and sealing checks

Global technical approach

The rotary airlock is as much an air-leakage control device as a dust discharge one

Selection is made based on capacity, pressure differential, rotor type, sealing, and wear.

Hantech Filter Rotary Valve / Rotary Airlock technical product selection

Rotary Valve / Rotary Airlock decision criteria

Product selection is made by evaluating site data, process risk, maintenance access, and operating cost together.

Information to be clarified before quotation

Material type, density, and flowability
Required capacity in kg/h or m³/h
Upper/lower pressure difference and hopper size
Existing valve diameter, rotational speed, and motor power
Wear, leakage, and jamming history

Capability

Cell volume, rotational speed, and fill ratio determine the kg/h capacity.

Tightness

Air leakage lowers cyclone/filter efficiency and disrupts bunker discharge.

Rotor Type

Open, closed, offset, or wear-resistant rotor is selected based on dust characteristics.

Safety

Jamming, bridging, ATEX, and maintenance access are operational risks.

Product / application comparison

Type / solution	App	Advantage	Caution point
Standard rotary valve	Filter hopper outlet, dry dust	Continuous, controlled discharge	Rotor/housing wear is monitored with abrasive dust
Heavy-duty rotary valve	Cement, minerals, lime, ash	Thick housing and high durability	Motor-gearbox torque and speed selection are important
Air lock / airlock valve	Lines with a pressure differential	Leakage air reduction	Rotor tip clearance and seals are critical
Food/chemical special valve	Lines requiring hygiene or corrosion resistance	Stainless-steel, easy-to-clean construction	Material certification and surface quality are required

Technical selection

What we evaluate together during the quotation process

Material name and bulk density, ton/hour capacity, particle size, moisture, temperature, line length, incline/elevation difference, operating duration, and connected equipment are all evaluated together.

Capacity and operating regime

Nominal/peak tons per hour, daily operating time, and feed continuity are calculated together.

Material and line geometry

Bulk density, particle size, moisture, abrasiveness, line length, and elevation difference determine the equipment type.

Drive, safety, and maintenance

Motor-gearbox, sensors, guards, service covers, and planned maintenance access are defined from the outset.
