Why does the air filter air volume become smaller?

Why does the air filter air volume become smaller? Shared by metal Filter Discs supplier.

Why is the air volume of air filter smaller? I believe that many customers have some doubts about this problem in the process of product use. Today we will explain several reasons why the air volume of air filter decreases.

First, confirm whether the final resistance of the air filter (that is, its reported value) has reached the final resistance during the use of the product. Generally, the final resistance value of the air filter is 400-600pa.

Two: whether the front end primary filter and the middle filter of the air filter have also reached the final resistance value. Because of the former primary effect, the middle effect mainly plays the role of protecting the air filter. If the front end primary effect and the middle effect filter has reached the reported destruction value, it will also affect the air volume of the air filter.

Three: air conditioning unit problem is not the air volume of the air conditioning unit in the use of the process has reached the whole purification space to the air volume.

Above is the air filter related content, hope to be helpful to you.

Air conditioning filter maintenance tips

Air conditioning filter maintenance tips shared by custom metal screen supplier.

Ac filter maintenance is very important for air conditioning unit, because it directly affects the degree of clean indoor air, so do the daily maintenance of ac filter is a key part of the central air conditioning unit maintenance. For the early effect and the effect of the air conditioning clean screen pack we should do it at least once a month, if the dust is more need to shorten the cleaning cycle, efficient air conditioning screen pack should be in accordance with the requirements for clean timely replacement.

Air conditioning filter screen cleaning should be used under 40 degrees of warm water, cleaning can not rub, when the air filter is dirty, we can use neutral detergent decontamination treatment, if the air filter is not very dirty, we can directly use water to clean.

After the air conditioning filter screen supplied by custom screen mesh manufacturer is cleaned, the water on the top is not enough to dry, and then put into the central air conditioning unit, in the air filter installation should pay attention to the air flow surface positive and negative, and strictly in accordance with the correct requirements for installation.

First we pour boiling water into the basin, and then go toward inside pour point right amount edible baking soda, stir to dissolve the water and baking soda, put the filter in the basin, big on 15 minutes, then the scrub with an old toothbrush or steel wire ball filter, on the surface of the oil is very easy to scrub down, than use the detergent do?

Cleaning construction method for Y type filter

Cleaning construction method for fan coil Y filter shared by Kitchen Sink Strainer supplier.

1. Close the inlet and outlet valve of chilled water of fan coil. Open the fan coil exhaust valve to drain water:

A. The discharge of the exhaust valve from large to small to anhydrous indicates that the inlet and outlet of chilled water are intact, and the second step can be continued;

B. The exhaust valve does not get out of water, and the exhaust valve may be blocked. Open the chilled water inlet valve and flush it out to remove dirt;

C. Continuous water discharge from the exhaust valve may lead to the possibility that the valve is not closed tightly. Tighten the frozen water and enter and exit the valve. Tighten the frozen water in and out of the valve, still water, indicating that the valve is bad, report to the supervisor.

2. Cut the insulation layer of y-type filter, open the screw cover of y-type filter, connect water with a container, and take out the filter. Open the outlet valve of chilled water, use the backwater pressure to backwash the waste in the heat sink until the water is out, and then close the outlet valve, install the filter after cleaning, and close the screw cover.

3. First open the chilled water inlet valve to exhaust the exhaust valve until the outlet valve grows out of water, and then tighten the drain screw of the exhaust valve to open the chilled water outlet valve.

4. Check the connection points of each valve for leakage.

A. No leakage, restore y-type filter insulation immediately;

6. If there is leakage, repair or treat the leakage point. And restore Y - type filter insulation layer.

5. Check the wind condition

A. Check the coil motor to determine whether the motor speed is normal, temperature is normal and sound is normal. Report any abnormality to relevant personnel immediately;

B. Check and clean the air filter and return air filter to ensure clean and smooth ventilation.

6. Check the discharge of condensed water. Remove dirt from the water tray and check whether the water outlet of the water tray is blocked. Water tray water, the most likely to produce algae sustenance, blocking the outlet, or even out of the pipe. If there's an algae bloom.

A. be sure to wipe thoroughly with a cloth. If the condensate outlet pipe is blocked by vitals, use the waste metal textile hose and blow it out.

B. Installation of water tray requires low outlet end to facilitate drainage. If there is water, check the height of the outlet end and adjust it. If it is difficult to adjust or there are other reasons, report to relevant personnel

Pre-packed Screens Description

Pre-packed sand control screens are designed using an inner and outer slip on wire wrap jacket screen of differing diameters which are secured together over a perforated base pipe. Thickness and size of medium filter layer depends on well requirements, such as formation size, flow rate, borehole size, etc.

Pre-packed screen used as stand-alone screen Pre-packed screen provide excellence service of sand control in oil, gas and water wells for its unique construction. Pre-packed screen is a modification of pipe-based wire wrapped screen. Its addition of a modular gravel pack makes it especially suitable for sand control where conventional gravel packing fails.

Pre-packed screens is an effective solution for keeping formation sand in its place. Gravel packing is used in conjunction with hydraulic fracturing, but at much lower pressures. Formation sand is produced from the breakdown of formations where wells are located. This occurs particularly in formations made of sandstone, limestone, and other similar types of rock. The main goal of gravel packed is to stabilize the formation and maintain well productivity.

The gravel sand or glass beads / quartz sand or ceramic or other proppant types medium filter is packed utilizing industrial vibrating machines to ensure a void free pack, and is then inspected utilizing high intensity light from the I.D. of the pipe to ensure proper compaction and distribution. The pre-packed assemblies can be manufactured to any desired coverage ratio on the pipe to work in coordination with rig pipe handling arms or to space out to cover specific zones within a reservoir.

Construction:
Pre-packed screen is comprised of six parts (from outer to inner) – outer screen, outer support rod, pre-packed gravel, inner screen, inner support rods and base pipe. This is a typical model of dual-screen prepack which features double wire wrapped screens.
The perforated base pipe is covered by inner wire wrapped jacket, whose diameter is smaller than the outer jacket. Between the two layers of jackets, an annular void is packed with silica sand with the appropriate size. The sand is coated by resin or ceramic beads. The gauge of the jacket wire is determined by the packed sand, while the size of the sand is determined by the formulation particle size distribution.

Materials:
Pre-packed screens can be fabricated in stainless steel 304, 316L, low carbon steel or other special alloys like Monel 400. Materials are available for specific alloy as required.

OEM size

Features:

Available in oil and gas well completions, especially in an open or cased hole with unconsolidated formations where stand-alone screen is needed.
Pre-packed screen is easy to install for its unique construction.
Stainless steel material gives it ability of resisting erosion.
Pre-packed screen is equipped with packed layer itself. This unique configuration eliminates gravel placement and significantly shorten the time of drilling a well.

What's wedge wire screen?

---the profile wires and the support rods.

Wedge Wire Screen, also named as Johnson Screen, is one of the most important product of YMX Filters. We have been involved in manufacturing the wedge wire screen for more than 10 years.

The wedge wire is a welded steel structure. It's fabricated by the profile wires, usually V-shaped, and sometimes other shapes, that are resistant welded onto the support rods/profiles. The distance between the profile wires are called the slot size. The slot sizes are controlled very accurately, so it result a very steady and reliable filter media.

The wedge wire screen, or we can call them the Johnson screen, is mainly used as filtration or separation materials. It's an ideal filter media. The triangle shaped wires/profiles between the slots will never cause a clog when solids pass though. When the solids pass through, the contact points are small and the tips of the slots are widened, so that the solids are less likely to clog, and even  when they the do clog, there will be a strong backside washing effect, resulting in excellent maintainability.

The structure of the wedge wire screen allows thicker profiles to form a thinner or smaller slot size. That means, this structure will be far strong and rigid compared to the woven or perforated filter screens. This make it very durable. What's more, the screen surface is smooth, the degree of wear is constant. And the stainless steel materials are very durable and steady, thus the wedge wire screen are very durable. They can be used almost indefinitely without replacement, reducing running costs. In addition, we are also able to produce Wedge Wire Screens using special materials such as titanium or duplex stainless steel.

Since it's significant advantages compared to other types of filter , the wedge wire screen products won it's popularity in many industries, like: water and waste water treatment, chemical industry,  water purifying, oil and petroleum, coal mining, agriculture, mineral resources, electric powder plants, food processing, pharmacy, paper, and many other industries.
