Ductless Tabletop PP Fume Hood

Cabinet Components

The cabinet is made of 8 - mm high - quality white - film - covered PP (polypropylene) boards. These boards possess excellent corrosion resistance. Seamless welding with color - matched welding rods is carried out to ensure the firmness and tightness of the cabinet.

Front and Side Panels

The main material for the front and side panels is ≥6 - mm acrylic board. It has extremely good weather resistance and outstanding chemical - resistance properties. It is not easy to age, is colorless and transparent, with light transmitting throughout, providing a comfortable visual experience and an elegant appearance.

Seven - inch LCD Touchscreen Display

Features a seven - inch LCD touchscreen with a high - definition display resolution of 1024×600, presenting a perfect visual system.

Real - time Temperature and Humidity Monitoring System

This system can display real - time temperature and humidity values. Users can set alarm parameters to ensure the safe use of the product.

Fan Monitoring

The fan monitoring function includes an alarm for fan system failures. The fan speed can be adjusted online to ensure that the air volume meets the requirements of different chemical operations.

Filter Saturation Alarm System

A saturation alarm value is set for the filter. Once it exceeds the set range, an alarm will be triggered, corresponding to the VOC concentration level. When both the alarm and the concentration level are high, the filter needs to be replaced.

Imported PSC Fan from the United States

Equipped with a 24 - volt PSC fan imported from the United States, which has stable performance, is ultra - quiet, and is free from sparks and static electricity.

High - efficiency Filtration System

The filtration system arranges and distributes filters according to particle size, following ASTM standards. It is highly effective in dealing with acidic gases and organic gases, with strong adsorption capabilities. For particles, a high - efficiency HEPA filter is used, achieving a filtration efficiency of 99.995% for particles larger than 0.3 μm.

LED Lighting

The power of the LED lighting is equivalent to that of a 25 - W fluorescent lamp. It does not generate heat, ensuring safety and not affecting the experimental environment temperature. It is energy - saving, environmentally friendly, and has a long service life.

Epoxy Resin Worktop

The epoxy resin worktop has excellent chemical stability, super - strong corrosion - resistance, good impact - resistance without damage, and outstanding high - temperature resistance. It is of one - piece core - through structure, has a long service life, and will not delaminate, expand, or crack.

Superiorities

Convenient Installation and Environment - friendly

There is no need for pipeline installation engineering. The installation is convenient, and the exhaust gas is not discharged externally, making it a new - type and environmentally friendly product.

Customizable Filtration Module

The top can be equipped with a filter module system according to experimental needs, meeting a variety of different experiments.

Advanced Modular Filtration Technology

The advanced modular filtration technology can completely adsorb and filter harmful gases, particulate dust, and other substances generated during experiments.

Energy - saving

It does not consume air - conditioning energy, saving energy efficiently.

Flexible Placement

It can be placed on the desktop or equipped with a mobile wheel base, being convenient and flexible, and suitable for any complex experimental location.

Working Principle

Air Inlet

Air is directly drawn from the laboratory into the fume hood, creating a negative pressure. The stable face velocity forms a natural barrier to separate users from the chemicals they are operating.

Comprehensive Filtration System

The fan system sucks the toxic and harmful gases upward. After filtration, clean air is returned to the room. The excellent concentration control of the cabinet can ensure that the chemical gases in the cabinet will not return to the room and cause pollution.

Purifying Laboratory Air

Different filters are configured according to different operations. This effectively filters toxic and harmful gases, purifies the laboratory air, removes chemical residue odors, and improves the cleanliness level of the laboratory.

Purifying the Surrounding Air

The continuous filtration efficiency of the fume hood can help purify the indoor air.

Parameter (Specification)

Feature And Application

Equipped with a seven - inch touch screen, it can monitor real - time temperature, humidity, wind speed, and VOC concentration. It also supports custom alarm parameters. A stable face velocity of 0.4 - 0.6 m/s creates a negative - pressure barrier. Coupled with a fault - diagnosis system (automatic shutdown in case of fan abnormalities), it ensures operational safety.

Application Scenarios

Suitable for the sub - packaging in hazardous chemicals warehouses, the maintenance of clean rooms in electronics factories, and the sample processing in hospital clinical laboratories. In the electronics industry, it can maintain the production environment for precision components. In the medical field, it effectively protects against biological hazards during blood sample processing.
