Early efficiency filters are used to filter the 5μm m more than dust particles, commonly used in air conditioning and ventilation systems and primary filter, but also for air conditioning and ventilation systems simply a filtering. Primary filter has a plate, folding, bag three styles, frame materials paper box, aluminum frame, galvanized iron frame, non-woven filter material, nylon mesh, activated carbon filters, metal hole net PROTECTION network has two-sided and double-sided galvanized wire barbed wire spray. Low cost, light weight, versatility, compact structure. Cleaning and washing can not be divided into two types.
 
 
Trapping 1-5um above dust particles and suspended solids.

According to customer demand non-standard primary filter  

1, according to the cleanliness of the environment on a regular basis (primary filter is generally 1 to 2 months) replacement.

2, on a regular basis (usually every two months) with a particle counter for measuring the implementation of this product cleanliness cleanliness purification area, when measured not match the cleanliness and cleanliness requirements, the reasons should be identified (for leaks and efficient if there is failure, etc.) if the early effect of the filter has expired, should be replaced with a new primary filter.

3. Replace the primary filter should be shut down.

 

Chart 1 activated carbon filter
Mainly used：
　　1, central air conditioning and ventilation systems pre-filter
　　2, pre-filter large air compressor
　　3, clean air return system
　　4, local high efficiency filter pre-filtration device
　　5, high temperature air filters, stainless steel frame, high temperature 250-300 ℃ filtration efficiency
This efficiency filters, G Series rough efficiency air filters in eight varieties, namely: G1, G2, G3, G4, GN (nylon mesh filter), GH (metal mesh filter), GC (active carbon filter device), GT (high temperature coarse filter).
 

Primary filter structure
The filter frame is sturdy waterproof plates to fix the folded filter completed. On frame diagonal is designed to provide a large filtration area, and internal filter tightly adhered to the outer frame. Four weeks begin with a special filter professional adhesive glue and adhesive frame, to prevent air leaks or pressure due to windage caused by the case of the occurrence of damage.

The filter material is folded in the form of loaded high strength and touch inside the cardboard, the frontal area is increased. Air flows into the dust particles are filtered material effective barrier between the pleats and folds. Clean air uniformly flows out from the other side, so the air flow through the filter is flat and uniform. Depending on the filter material is different, they block a particle size from 5μm m to　5μm m different filtration efficiency is different!

 

Bag filter maintenance and repair
    1, according to the cleanliness of the environment on a regular basis (primary filter is generally 1 to 6 months) to be replaced.
　　 2, on a regular basis (usually every two months) was determined by purifying the product embodiment cleanliness cleanliness area with dust particle counter, when measured not match the cleanliness and cleanliness requirements, the reasons should be identified (leaks and efficient if there is failure, etc.) If the high efficiency filter has expired, should be replaced with a new high efficiency filter.
　　3, to replace the primary filter should be shut down.
 
Cleaning instructions
    1, open the device for the intake grille, hold down the button on both sides and gently pull down;
　　2, holding the hooks of the air filter on the obliquely downward pull equipment;
　　 3, a similar vacuum cleaner dust equipment erase, or rinse with warm water;
　　4, if you encounter excessive dust then you can add a neutral detergent to clean with a soft brush, clean water after drying, placed in the shade to dry;
　　5, do not use more than 50 ℃ hot water for cleaning equipment to avoid discoloration or deformation of the phenomenon, and do not roast on the fire;
　　6, after completion of the cleaning and make sure the fashion equipment, the installation of the devices on the upper portion of the projection portion of the suction grille and then fixed to the top of the suction grille, the rear suction grille to the shank slowly slide inside until the entire device is pushed into the grid;
　　7, the final step is to close the intake grille, which is exactly the opposite, and the first step, press and hold the filter control signal reset button on the disc, this time cleaning reminder symbol will disappear;
　　8, in addition to remind you that if the early effect of the filter used excessive dust environment, then the number should be cleaned, as the increase in, usually every six months is appropriate.
