The Supplemental Ventilation Cabinet SJHB PP21 suits chemical-synthesis settings with mild corrosion and dense arrays of fume hoods, where stable exhaust and minimal energy use both matter.
Its cabinet body, deflector, and collection hood are made entirely of PP board for strong acid-, alkali-, and corrosion resistance. Structural optimization increases usable interior space while keeping the body stable, with a load-bearing capacity of up to 200 kg.
A distinctive air-supplement structure introduces make-up air close to the face, reducing operator interference with the internal airflow and ensuring rapid, effective exhaust of waste gas. With a design air volume of 1,100 m³/h at 0.5 m/s and a leakage rate below 0.05, it delivers over 60% energy savings versus conventional exhaust cabinets—an advantage that compounds across multi-hood laboratories.
Third-party tested to CMA, CNAS, and ILAC-MRA standards and compliant with ASHRAE 110-2016 and JB/T 6412-1999. Available in 2350×850×1200/1500/1800 mm.
