The DPA pocket filter is a high-efficiency air filtration unit designed specifically to capture over-spray paint mist in dry-type spray booths; its core features a special synthetic fiber material and a 3D honeycomb-like, multi-layered structure.

Activated carbon cotton air filters combine physical dust removal with chemical adsorption. Utilizing synthetic fiber cotton as a substrate—onto which activated carbon powder or fibers are bonded via impregnation or adhesion processes—they are primarily used to remove odors, harmful gases (such as formaldehyde), and fine dust from the air.

The Metal mesh air filters are constructed from multiple layers of corrugated aluminum foil mesh or stainless steel wire mesh. Its key features include high airflow capacity, low resistance, and re-usability through washing. It is typically used to capture large dust particles, debris, and oil mist from the air.

The G4 primary filter is a coarse air filtration designed primarily to capture large dust particles and protect downstream precision filters and air conditioning systems; its key performance metric is a filtration efficiency of approximately 70%–90% for 5-micron particles. It is widely used for pre-filtration in centralized ventilation and central air conditioning systems.

The Regenerative Thermal Oxidizer (RTO) primarily consists of a heat storage chamber, an oxidation combustion chamber, switching valves, a burner, gas supply and combustion-supporting systems, a compressed air system, and a control system. The operation of these components is interlocked, ensuring stable performance.
