What are the requirements for a high-performance exhaust fan?

Most common household kitchens use fume hoods for fume exhaustion, but kitchen kitchen hoods, which have too much fume, are not able to meet the requirements of fume exhaust. Therefore, these kitchens are generally used. Large exhaust smoke exhaust fan. And if a smoke exhaust fan wants to satisfy the restaurant kitchen exhaust fumes and fire smoke in other places need their own high performance, which requires it to meet many requirements.

1, has a very good high temperature performance, can meet the discharge of high temperature fumes and high smoke efficiency, installation is very convenient to occupy a small space before meeting the basic requirements of high-performance exhaust fan.
2. High-temperature exhaust fan's high-temperature resistance is not only required to be expressed in the exhaust fumes, but also should be able to remain in the high temperature environment for a long time while continuous operation is not damaged. The fan can meet more use requirements.
3, its air volume should be in line with the relevant standards, and the full pressure value error is small, the noise during operation should also be very small.
Of course, as the exhaust gas fan is the most basic ability and efficiency of the exhaust, so the high-performance fan must have advantages in this regard, so as to be able to meet the needs of the kitchen and other fire smoke emissions.

PVC capillary Drainage Board is made of laminated soft rubber material, and the dense slot is opened on soft rubber plastic material. The slot hole is designed to be small inside and big outside and when you use it you should let the hole facing down. Using the principle of capillary water absorption, the water flow is poured from the bottom up to the capillary sink. The soil particles in the water will naturally precipitated by gravity, and the soil particles will not enter into the capillary water pipe, and will not generate siltation near the water channel. PVC Drain Board can produce excellent water absorption and drainage.

Product features

1. Non-blocking: use of natural gravity to separate soil and water;

2. High permeability property: 20% open hole rate has effective water absorption area;

3. High drainage efficiency: drainage board using capillary force to improve drainage efficiency;

4. Strong anti-earth pressure: arch bridge structure design, effective dispersion of stress distribution with self-cleaning function,

5. Convenient construction: the drum package will not take up the volume and reduce the transportation cost, storage, management, work cost

7. Flexibly: can be closely combined with the topography to form an infinite long, compressed highway;

8. Durability: Stoma Drainage Plate made from PVC high density polymerization material, so PVC drain board has the advantage of uv resistance and durable.

Golf course underground drainage and slope drainage, underground irrigation in arid regions, park or green space underground drainage, low wetland agriculture drainage, retaining wall and tunnel engineering field underground drainage, iron highway roadbed drainage and underground drainage, rainy season gardening landscape water supply and drainage, etc.

Basic construction specifications

In principle, the hole groove (absorbent surface) can be roughly downward, so that the soil particles can be settled by gravity to prevent blockage.

At least two percent of the embedding slope are recommended to generate siphon-age

Lay the bottom of the ditch to be leveled, compacted, then laid the wool and fine drainage belt.
