Primary Plate Air Filter
It is used in combination with HEPA filters to prevent premature replacement of HEPA filters due to dust accumulation, thus extending the service life of HEPA filters.
High-quality filter media, reasonable design, high dust holding capacity and low resistance
The high-quality fluffy filter media is used. The filter media is a special mixture of non-woven fabric and synthetic fiber, with a special contour pleat design to provide a larger dust holding capacity and increase the utilization of the filter media. A reasonable number of filter pulp pleats increases the effective use area of the filter and reduces the resistance at the same time.
Sturdy double-layer moisture-proof paper frame structure
GroAir primary-efficiency plate filter adopts moisture-proof paperboard frame, and the filter paper is bonded to all the connection points in the frame, which has a solid and reliable structure and ensures that the filter will not be deformed or damaged under the poor usage environment. Supplemented with filter media support mesh inside, the filter enjoys compact structure, light weight, easy installation and disassembly.

Washable Primary Panel Filter
GroWash is used in industrial and commercial HVAC systems.
1. Ventilation and air conditioning systems for office buildings, hospitals, shopping malls, gymnasiums, airports and other large civil buildings.
2. Centralized HVAC systems for general industrial plants.
3. Pre-filtration of the centralized ventilation and air conditioning systems for cleanrooms.
High-quality filter media, reasonable design, high dust holding capacity and low resistance
The high-quality polyester synthetic fiber is used, which ensures fluffy air inlet and tight air outlet of the filter, providing a large dust holding capacity while ensuring filtration efficiency. The reasonable design of filter element pleats increases the effective filtration area, while reducing the resistance and increasing the dust holding capacity.
Aluminum frame, sturdy and light weight, easy to install and disassemble
GroWash primary-efficiency plate filter is made of surface aluminum oxide extruded profile, supplemented with filter media framework inside, thus enjoying compact structure, light weight, easy installation and disassembly.

High-quality synthetic man-made fibers
Stable structure and reliable performance

Medium Pocket Filter
FeinPak is ideal as a medium-efficiency filter for use in humid, high airflow and high dust load environments and is widely used in air conditioning ventilation systems for pharmaceutical, automotive, food processing, commercial buildings and other industrial uses.
Compact and lightweight
The frame of FeinPak medium-efficiency bag filter can be made of galvanized iron or aluminum alloy, supplemented by iron framework for bag support, which not only effectively supports the bag but also maximizes the filtration area. The filter features compact and sturdy structure and easy installation and disassembly.
High-quality multi-layer polyester filter media, high dust holding capacity, and low resistance
The high-quality multi-layer polyester synthetic fiber is used, which ensures fluffy air inlet and tight air outlet of the filter, providing a large dust holding capacity while ensuring filtration efficiency. A reasonable number of filter bags increases the filtration area and dust holding capacity, while reducing the resistance.

Medium Efficiency Box Type Separator Filter
FeinAir I medium-efficiency separator box filter is widely used in the medium-efficiency filtration section of ventilation systems for various industrial, commercial and civil buildings for its extended filter surface of high air volume, compact structure and light weight.
Preferred material, sturdy structure, easy transportation and installation
The high-quality fiberglass filter paper is used, with coarser fibers on the inlet side and finer fibers on the outlet side. It can make full use of the area and depth of the filter media to maximize the dust holding capacity, thus extending the service life of the filter and reducing operating costs. The extended filter surface with corrugated aluminum separator maintains a uniform fold space and increases the strength of the filter to adapt to the pressure on the filter caused by various air volume changes. It also effectively prevents damage to the filter in transit. Smaller thickness and sturdy construction make it easier to install and disassemble.

Medium Efficiency V-bank Filter
FeinAir V is a V-bank box filter with large load, consisting of multiple separator-free filter elements in a V-shaped structure (available in 3V/4V/5V).
This structure can accommodate more filter media (30-40% more filter media than ordinary box filters) to fully increase the filtration area, so that the filter pressure loss is reduced and the dust holding area is increased, thus reducing energy consumption and saving operating costs.
Both GL and ABS are available. The unique ABS resin outer frame design ensures a stronger structure and lighter weight for easy transportation and installation.

High Efficiency Separator HEPA Filter
PuriCel I separator box filter is widely used in the high-efficiency filtration section of ventilation systems for various industrial, commercial and civil buildings for its extended filter surface of high air volume, compact structure, light weight and undergoing UL900 certification.
High air volume PuriCel I filters are suitable for higher air volume applications than their standard air volume counterparts, offering flexibility and cost savings.
Higher face velocity (up to 2.5 m/s with little increase in initial pressure loss)
Compared with standard air volume filters, PuriCel I has lower resistance, less energy consumption and longer service life with the same air volume.

HEPA Mini-pleat Filter
Compact structure, easy installation and replacement
The Puricel II frame is made of aluminum extruded profile, and the imported phosphorus-free polyurethane adhesive is used to seal the waterproof and flame-retardant fiberglass filter element which is spaced by hot melt adhesive, supplemented by the surface protective mesh, sealing gasket and other components. It features a compact structure, small and light, easy installation and replacement.
Comprehensive leak testing to ensure no leaks
The industry's advanced environmental-friendly water-based aerosol leak detection platform is used for testing without secondary pollution, to ensure that each piece of filter is leak-free.
Testing efficiency according to EN1822
According to EN1822 standard, the United States PMS laser particle counter and PSL test particles are used to test the efficiency of the filter using the most penetrating particle size (MPPS) method to ensure that the filter efficiency meets requirements.

HEPA V-bank Filter
Excellent design, high-density filter media, and targeted filtration
PuriCel II HEPA filter has excellent filtration of tiny particles in the air. The filter element is made of high-quality fiberglass filter media (pleated) with a linear hot melt adhesive strip separator to minimize the resistance to air. V-shaped structure assembly is adopted to hold more filter media.
Air volume up to 4000 m/h, saving installation space
PuriCel II is designed with higher air volume for high air volume environments, so the number of filters used in the fresh air system is reduced under the same air volume, saving space and reducing energy consumption. In existing systems, the PuriCel II's large filter area ensures a low resistance and reduced operating costs.

Gel Seal HEPA Filter
Gel seal design to ensure perfect sealing
By adopting international brand gel seal design, the filter has excellent chemical stability, corrosion resistance, mildew resistance, bacteria resistance and moderate hardness. Even after repeated assembly and disassembly, it can still maintain a good seal after a period of time.
