Clean gas type fume hood JG/T385:2012 Related working principle Shanghai Litao

Clean-type fume hood JG/T385:2012 Related working principle Shanghai Litao working principle: 1, the air inlet air can be directly pumped into the fume hood from the laboratory, forming a negative pressure, stable surface wind speed to form a natural barrier to isolate users and the chemicals
they operate.
2, the comprehensive filtration system fan system will inhale toxic and harmful gases upwards, filtered, return clean air to the room
.
The excellent controlled concentration of the cabinet body can ensure that the chemical gases in the cabinet body will not return to the room, causing pollution
.
3.
Clean laboratory air according to different operations with different filters, effectively filter toxic and harmful gases, purify laboratory air, remove chemical residual odor, improve laboratory cleanliness level
.
4.
The continuous filtration efficiency of the fume hood that purifies the surrounding air can help purify the indoor air
.
Product features: 1, metal parts: the main material ≥ 1.
2mm galvanized steel sheet, epoxy resin electrostatic spraying, covered with durable anti-chemical lead-free coating, to maintain high finish and * to a maximum extent to reduce the impact
of corrosion and moisture.
2, the front plate and side panel: the main material ≥ 6mm acrylic plate, weather resistance * good, chemical resistance, not easy to aging, colorless and transparent, transparent throughout, visual comfort, beautiful and generous
.
3.
Real-time temperature and humidity environment monitoring system, display temperature and humidity, set alarm parameters, and ensure product safety
.
4.
Fan monitoring: fan system failure alarm, online adjustable fan speed, to ensure that different chemicals operate air volume
.
5, filter saturation alarm system: the product is equipped with a double filter and double VOC probe, a probe to monitor indoor air quality, a probe to monitor the filter saturation status, the filter set saturation alarm value, out of range that is, alarm, when the concentration exceeds the set value for a long time to replace the filter
.
6, PSC fan, 24 volt voltage, stable performance, silent, no spark static
.
7, high-efficiency filtration system, according to the particle size selection arrangement, follow the ASTM standard, effective for acid gas and organic gas, strong adsorption capacity, for particles using high-efficiency HEPA filter, for particles greater than 0.
3um, filtration efficiency of 99.
995%.

8, LED lighting power equivalent to 25W fluorescent lamp, does not produce heat, safety does not affect the experimental ambient temperature, energy saving, environmental protection, long
life.
9.
The epoxy resin table has chemical stability, C strong corrosion resistance, good impact resistance without damage, excellent high temperature resistance, integrated core penetration, long service life, no delamination, no expansion, no cracking
.
