Aishin Industrial (Thailand) offers the “Double-Link Damper”, a powder and granule discharge system for smooth discharge of particulate materials from bag filters and cyclones. In this article, we will introduce the unique technology, features, and lineup of this product.

Simple operation and smooth motion extend the life of equipment! Solenoid valves and control panels are cost-effective and energy-saving!

The double-link damper is a system used for the discharge of particulate materials, and is installed to , such as by preventing backflow of air in bag filters and cyclones. Two dampers are used at the end of the pneumatic transport to shut off the air and ensure smooth discharge.



【Features】
・Air shutoff function ensures efficient discharge of powder and fine particles
・Simple operation with two-stage lock function controls the discharge process
・Compared to other products, the compact design makes it ideal for locations where space is limited
・One air actuator smartly opens and closes the upper and lower dampers
・Smooth motion extends the service life of the equipment
・Cost reduction of solenoid valve and control panel
・Smart energy-saving and maintenance-saving design
・Suitable for discharging materials from bag filters and cyclones
・Standard size: 150mm / 200mm / 250mm / 300mm

【Other product lineup】
■ Double-flap damper
Used in a wide range of industries such as batteries, chemical products, and food products as discharge applications for cyclones and dust collectors.

■ Sanitary flap damper
Features a highly sanitary design with a removable valve disc drive unit that can be disassembled and cleaned. Ideal for food and pharmaceutical manufacturing sites.

Unique mechanism with single control saves cost, energy and maintenance

The double-link damper is a unique mechanism in which single cylinder is linked to two-stage upper and lower flap dampers, and alternately opens and closes, saving energy and maintenance.

Based on the standard double-flap damper structure, which has remained unchanged for more than 30 years, it has evolved into a simpler, more cost-effective design. Eliminating expensive machining and complex structures, it can be installed at a more affordable price than double-flap damper.

【Unique technical mechanism】
・Two-way operation of the cylinder
The ability to operate two functions with a single cylinder allows for a compact design and improved space efficiency.

・Single control of solenoid valve
Control that normally requires two solenoid valves can be performed with a single solenoid valve, simplifying the control process and reducing costs.น

・Easier maintenance and cost reduction
Simpler design and more efficient operation reduce control complexity, resulting in cost savings of 20-30% and reduced maintenance costs compared to the existing products.
