High-Performance Heavy-Duty Air Filter Making Machine for Reliable Large-Scale Production

The high quality Hdaf Horizontal Gluing Machine is offered by Pulan, a leading China manufacturer. It is specifically designed for hot-melt adhesive dispensing on cylindrical and conical large air filter elements. The equipment supports three dispensing patterns—linear, circular, and spiral—and allows for simultaneous or independent dispensing on the inner and outer diameters. Featuring a touchscreen and PLC control system, it offers intuitive operation and stable performance, ensuring the structural integrity of the filter element even under high pressure. This machine is an excellent investment and a highly efficient solution for the gluing process of large air filters.

Buy a high-quality, Full-Auto Hot Melt Filter Paper Bonding Machine from a Pulan factory in China. It uses hot melt adhesive, which is melted at high temperature and precisely poured through a dispensing head. Dual synchronous belts clamp and extrude the finished product. The inlet features infrared dual control (positioning and dispensing), and upper and lower panels with guide blocks prevent filter cartridges from falling off. Production capacity is adjustable from 10 to 30 pieces/minute, ensuring strong bonding and smooth joints.

Pulan Factory offers a high-quality Full-Auto Casting Machine On Seal Packing In Filter Element designed specifically for the gasket dispensing process of hydraulic filter elements. It features computer-controlled operation with digital displays, ensuring stable and precise metering and automatic, constant-temperature control of the material. The machine boasts a unique dispensing head design with precision micro-adjustment for material recirculation, ensuring stable and efficient performance. It supports automatic casting for circular gaskets up to 450mm in diameter, with a dispensing rate of 5–30g/s; the dispensing head automatically shifts 450mm after casting and includes an automatic cleaning function. Easy to operate and highly reliable, this machine is an ideal choice for filter gasket production.

Pulan (China professional manufacturer of spin-on machines and diesel production equipment) launched the A B Two Compounds Filter End Cap Gluing Machine, a highly efficient automated device specially designed for two-component adhesive potting of filter element end caps such as air conditioning filters. It adopts a touch screen and PLC intelligent control system. The turntable-type dispensing works in combination with a stepper motor, featuring fast glue output and short return travel, ensuring uniform and stable adhesive application. The whole machine is equipped with heating and mixing, self-limiting temperature heating for pipelines, anti-curing alarm, and self-inspection maintenance systems, ensuring precise and reliable glue output, significantly improving bonding efficiency and consistency of end cap products.
