          Intelligent Lab Fume Hood Factory From SUCLAB Company    1,The intelligent fume hood is an advanced Lab Fume Hood Factory with excellent air purification capacity, which can effectively control the concentration of air pollutants in the laboratory. The variable air volume (VAV) control system of the Lab Fume Hood Factory is an important component to ensure its normal operation. Now, let's take a look at the principle of this control system.     2,The variable air volume control system of the Lab Fume Hood Factory includes sensors, actuators and controllers. The sensor can measure parameters such as indoor temperature, humidity, pressure difference and pollutant concentration. The controller adjusts the working state of the actuator based on the feedback signal from the sensor and controls the size of the air supply volume.    3,The Lab Fume Hood Factory variable air volume control system can also automatically adjust according to different working conditions inside the laboratory. For instance, when chemical reactions are taking place in the laboratory and the concentration of pollutants is relatively high, the controller will automatically adjust the air supply volume based on the feedback signals from the sensors to ensure the stability of the indoor air quality. In conclusion, the variable air volume control system of the intelligent fume hood is an important component of the intelligent fume hood. This system can automatically adjust the supply air volume according to different working conditions and pollutant concentrations inside the laboratory to ensure the stability of air quality and temperature within the laboratory. At the same time, it can also be manually adjusted through the human-machine interface.   Photos:        

                                              Fume Hood Solution In Laboratory           The main function of a fume hood solution  is to suppress the harmful chemical gases produced inside the hood, prevent their leakage, and expel them from the laboratory as soon as possible to protect the safety of laboratory staff. Fume hoods are an important component of laboratories. The function of a fume hood is to discharge various indoor exhaust gases. Fume hoods are commonly used laboratory equipment. During experiments, they are required to discharge harmful gases and clean up pollutants. The main function of a fume hood: The most important function of a fume hood is the exhaust function. In a chemistry laboratory, various harmful gases, odors, moisture, flammable, explosive and corrosive substances are produced during experimental operations. To protect user safety and prevent contaminants from the experiment from spreading to the laboratory.         1. Release function: Fume hood solution should be equipped with a mechanism that dilutes the harmful gases generated inside the fume hood by absorbing the outside air and then discharges them outdoors. Isolation function: There should be a non-sliding glass window in front of the fume hood to separate the inside and outside of the fume hood. Heat resistance and acid and alkali corrosion resistance: Some fume hoods need to be equipped with electric furnaces, and some experiments produce a large amount of toxic and harmful gases such as acids and alkalis, which are highly corrosive. The countertop, backing board, side panels of the fume hood, as well as the selected faucets and air nozzles, etc., should all have anti-corrosion functions. In the semiconductor industry or corrosive experiments where strong acids such as sulfuric acid, nitric acid, and hydrofluoric acid are used, it is also required that the overall material of the fume hood must be resistant to acids and alkalis, and it must be made of stainless steel or PVC materials. 2. Non-backflow function: Fume Hood Solution should have the function that the airflow generated by the exhaust fan inside the fume hood can prevent harmful gases from flowing back into the room from the inside of the fume hood. To ensure the realization of this function, it is the best way to connect one fume hood with one ventilator through a single pipe. If a single pipe connection is not possible, it is only allowed to be connected in parallel in the same room on the same floor. The ventilator should be installed at the end of the pipe (or at the top of the floor) as much as possible. 3. Supplementary function: It should have a channel or alternative device for drawing in air from outside the fume hood when discharging harmful gases. Jiangxi Huzhijun Technology Co., Ltd. takes "Customer satisfaction is the sole criterion for evaluating our work" as its service tenet, and always adheres to taking customer needs and satisfaction as the core, with the mission of building a modern scientific laboratory that is safe, environmentally friendly and comfortable.     

Polypropylene Lab Fume Hood with Built in Scrubber is A Best Way for Acid Alkali   Waste Gas Treatment of Fume Hood     Polypropylene fume hood with built in water scrubber  is a two safety features into one, providing double protection Specifcitions : Polypropylene fume hood with water scrubber system treating from Acid alkali Exhaust wate Gas of fume hood : A fan system effectively removes harmful gases, vapors, dust, and aerosols generated during operation, preventing their spread within the laboratory. Physical Isolation: The front window (viewing window) provides a physical barrier for operators, preventing direct injury from splashes, explosions, or flying debris that may result from chemical reactions. Operating Platform: Provides a dedicated, corrosion-resistant space for experiments involving chemicals. Immediate Rinsing: The spray system can be activated immediately in the event of accidental splashing of corrosive, irritating, or toxic chemicals (such as strong acids or alkalis) onto the operator's body, face, or eyes. Dilution and Removal: A large, continuous flow of clean water rapidly dilutes and washes away chemicals from skin or eyes, minimizing chemical damage and buying valuable time for subsequent medical treatment. Compliant with safety standards: Its design must meet safety standards (such as ANSI Z358.1) to ensure that emergency equipment is "reachable within 10 seconds" in the event of an accident, and this design directly reduces rescue time to "within 1 second." The choice of PP material is closely related to the "water spray" function, making it particularly suitable for handling these types of chemicals: Polypropylene fume hood with built in water scrubber  is Excellent corrosion resistance: PP plastic has excellent corrosion resistance to most inorganic acids, alkalis, and salt solutions (such as hydrochloric acid, sulfuric acid, nitric acid, sodium hydroxide, etc.). This is precisely the type of chemicals that easily cause splashes and require emergency rinsing. Seamless welding, no leakage: High-quality PP fume hoods are typically welded using homogeneous welding rods, without seams or gaps, ensuring that corrosive liquids will not leak into the cabinet and cause structural damage or contamination. Non-conductive, high safety: As an insulating material, it is safer in experiments involving electrical equipment. Light weight and high strength: Compared to steel fume hoods, it is lighter, but its structural strength is sufficient for daily use. In short, the PP material ensures that the fume hood itself will not be corroded or damaged when exposed to chemicals requiring emergency rinsing with water, guaranteeing the long-term durability of the equipment. Applicable Scenarios : This water-spraying PP fume hood is ideal for the following laboratory environments: High-intensity inorganic chemical experiments: Laboratories using large amounts of concentrated acids and alkalis, such as chemistry teaching laboratories, quality control centers, and wastewater treatment laboratories. Wet digestion/sample pretreatment: Experiments involving the heating and digestion of samples with strong acids (such as nitric acid and sulfuric acid), with a high risk of splashing. Electroplating solution analysis and testing. Any location where safety is the highest priority and primarily handles corrosive chemicals. Important Precautions : This is not a replacement for all safety equipment: It is primarily intended for handling splashes of corrosive chemicals. For fires, fire extinguishers are still required; for large leaks of toxic gases, immediate evacuation is still necessary. Water Source and Drainage: Water Supply: A continuous and stable clean water source (usually tap water) must be connected, with water pressure and flow rate meeting standards (e.g., spray head flow rate ≥ 75.7 liters/minute). Drainage: The fume hood must be equipped with a drip tray and drain outlet to collect and discharge the large amounts of wastewater generated during rinsing. This wastewater may need to be directed to a neutralization tank or a dedicated wastewater treatment system and cannot be directly discharged into ordinary sewers. The PP fume hood with water shower (emergency spray) is a safety workstation tailored for high-risk corrosive chemical environments. Utilizing PP material to resist daily corrosion and providing immediate emergency rinsing capabilities through an integrated spray system, it achieves seamless integration of "routine control" and "emergency rescue," serving as a solid line of defense for the safety of laboratory personnel.     Polypropylene Lab Fume Hood with Built in Scrubber Design Soluitons:           Technical Parameters :   Model Polypropylene Lab Fume Hood with Built in Scrubber Material Cabinet shell 8mm polypropylene Plate Frame Up and down Shape Square Size 1200/1500/1800*1100*2350 mm Other Size Custom Window 5mm thk tempered explosion-proof glass or pc plate , with handle using alum alloy epoxy coating, opening capacity 200mm ≤ H ≤ 750m; Worktop 12.7mm thickness Phenolic board, Ceramic board; TRESPA epoxy resin board; Control panel Glasses touch panel, able to control the air volume and window opening, with emergency exhausting and sensor of movement, Lining 5mm thk durable Phenolic integral work walls LED strips The lamp is hidden under the roof, luminosity ≥ 800LUX Breaker IP65 Standard feature Equipped with pp sink and faucet, Optional fittings Explosion-proof socket VAV control system External face velocity display device Quality Control We strictly control the production process and record all production process for your review Loading Port Shenzhen/Guangzhou port Company Profile   And Working Priciple :       Polypropylene Lab Fume Hood Functions:   Cabinet and door: made of 8mm high quality white polypropylene(PP)sheet with excellent feature on chemical resistance.
