Ductless Tabletop Steel Fume Hood

Guangsheng Technology is a professional fume hood manufacturing factory. The ductless tabletop steel fume hoods produced by it can be optionally equipped with a top - mounted filtration module system according to experimental requirements. There is no need for additional pipeline engineering, and the installation is convenient. Moreover, it is equipped with a fan system with adjustable speed to ensure the safety of non - discharge of exhaust gases.

The ductless air-purifying fume hood series complies with the NFX 15 211:2009 standard (certified by ANSI Z 9.5 - 201), the ASHRAE 110:1995 standard, and the Chinese national standard JG/T385:2012. It is also ISO9001 certified. Specifically designed to protect the safety of laboratory personnel during experimental operations, this product prevents operators from inhaling toxic, harmful, disease-causing, or chemicals of unknown toxicity during experiments. It efficiently purifies the air inside the fume hood and the laboratory, providing safety protection for laboratory personnel.


Product Features

Metal Components: The main material is galvanized steel plate with a thickness of ≥ 1.2 mm. It is electrostatically sprayed with epoxy resin and coated with a durable, chemical-resistant, lead-free coating, which maintains a high degree of smoothness and minimizes the impact of corrosion and moisture.

Front and Side Panels: The main material is acrylic plate with a thickness of ≥ 6 mm. It has excellent weather resistance, outstanding chemical resistance, is not prone to aging, is colorless and transparent, with overall light transmission, providing a comfortable visual experience and an aesthetically pleasing appearance.

*3. Seven-inch LCD Touch Screen Display: With a high-definition display resolution of 1024 * 600, it offers a perfect visual system.

*4. Real-time Temperature and Humidity Environmental Monitoring System: It displays temperature and humidity and allows users to set alarm parameters to ensure the safe use of the product.

*5. Fan Monitoring: An alarm will be triggered if the fan system malfunctions. The fan speed can be adjusted online to ensure the air volume required for different chemical operations.

*6. Filter Saturation Alarm System: A saturation alarm value is set for the filter. An alarm will be triggered once the value exceeds the range, 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: Operating at 24 volts, it has stable performance, is ultra-quiet, and generates no sparks or static electricity.

High-efficiency Filtration System: The filters are arranged and distributed according to particle size, following the ASTM standard. It is highly effective against acidic and organic gases, with strong adsorption capacity. A high-efficiency HEPA filter is used for particles, achieving a filtration efficiency of 99.995% for particles larger than 0.3 μm.

LED Lighting: With a power equivalent to a 25W fluorescent lamp, it does not generate heat, is safe, and does not affect the experimental environment temperature. It is energy-saving, environmentally friendly, and has a long lifespan.

Epoxy Resin Tabletop: It has superior chemical stability, excellent corrosion resistance, good impact resistance without damage, outstanding high-temperature resistance, an integral through-core structure, a long service life, and will not delaminate, expand, or crack.


Advantages

No Pipeline Installation Required: It is easy to install. The exhaust gas is not discharged externally, making it a new type of environmentally friendly product.

Optional Filter Module System on the Top: The top can be optionally equipped with a filter module system according to experimental requirements, meeting the needs of various different experiments.

Advanced Modular Filtration Technology: It can completely adsorb and filter harmful gases, particulate dust, and other substances generated during experiments.

No Air Conditioning Energy Consumption: It efficiently saves energy.

Flexible Placement: It can be placed on a desktop or equipped with a mobile wheel base, which is convenient and flexible, suitable for any complex experimental location.


Working Principle

Air Inlet

Air can be directly drawn from the laboratory into the fume hood, creating a negative pressure. A stable surface wind speed forms a natural barrier to isolate users from the chemicals they are operating.

Comprehensive Filtration System

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

Purify Laboratory Air

Different filters are configured according to different operations to effectively filter toxic and harmful gases, purify the laboratory air, remove chemical residue odors, and improve the laboratory cleanliness level.

Purify the Surrounding Air

The continuous filtration efficiency of the fume hood helps to purify the indoor air.

Feature And Application

The ductless fume hood with purified air has remarkable features. In terms of materials, the metal components are made of galvanized steel plates with a thickness of ≥1.2mm. Through special processing, they are robust and corrosion - resistant. The front and side panels are made of acrylic plates with a thickness of ≥6mm, which are weather - resistant, chemical - resistant and transparent, facilitating operation and observation.

Functionally, it is equipped with a 7 - inch 1024*600 high - definition touch - screen, integrating functions such as temperature and humidity monitoring, fan and filter status monitoring. The operation is intuitive and allows for precise control. It has a powerful filtration performance. The filters are arranged according to ASTM standards, with strong adsorption capacity for acidic and organic gases. The HEPA filter has a filtration efficiency of 99.995% for particles larger than 0.3um. The fan is a 24 - volt PSC fan imported from the United States, with stable performance, quiet operation and no static electricity. It optimizes the air circulation and filtration mechanism by itself, eliminating the need for air - conditioning energy consumption, thus being energy - saving and environmentally friendly. In addition, the LED lights generate no heat and have a long lifespan. The epoxy resin countertop has good chemical stability, being corrosion - resistant, impact - resistant and heat - resistant, reflecting a user - friendly design.

In terms of applications, the fume hood has a wide range of applicable scenarios. It is an important device for ensuring experimental safety in conventional chemistry, biology, and pharmaceutical laboratories. In electronic chip manufacturing laboratories, it can filter out harmful gases generated during photolithography and etching processes, maintaining a precise experimental environment. In food testing laboratories, it can remove odors and harmful gases volatilized from chemical reagents, ensuring accurate test results. In forensic evidence laboratories, it can handle potential bio - hazardous substances and chemical gases generated during DNA extraction and chemical analysis, protecting the safety of personnel. In the future, the fume hood will develop towards intelligent integration. It will be integrated with the LIMS system to achieve remote monitoring and operation. Moreover, filter materials for emerging pollutants will be developed, and energy - saving designs will be optimized, enabling it to play a role in more fields.
