This device is mainly used for conducting operations in ordinary environmentsSPF animal experiments. It consists of three parts: the host, the cage frame, and the cage box. Indoor air enters each individual cage on the air duct frame through the air supply filtration system. Provide uniform, low velocity clean air for SPF animals, and trap the waste gases emitted by the animalsThe return air duct enters the main exhaust system, and after filtering, it is discharged outdoors. In order to maintain the ammonia concentration and humidity inside the cage, reduce the frequency of material replacement, effectively prevent animal cross infection, and ensure the health and safety of experimental workers. This device consists of one machine and two machines50 cages, polysulfone PC cage box, digital host.

1. Stainless steel digital host

GermanyEBM motor, HEPA with high-efficiency filtration efficiency of 99.999% without partitions,The exhaust system is equipped with an activated carbon filter, odor removal function, pointer differential pressure gauge, and LCD screen temperature and humidity meter

Equipped with power outage alarm auxiliary function, the system has cumulative startup time function, which can be used as a replacementHEPAEstimated value of filter, 304/2B stainless steel plate chassis, can be disinfected by drug fumigation, with4-inch wear-resistant polyurethane casters, flexible in movement

2. Stainless steel cage frame(5 layers x 5=25 cage positions)

1 host is the most available for supplyThe air volume of 2 cage frames and boxes, i.e. 2 frames per machine:

The cage frame has a fine adjustment function: by adjusting the fine adjustment device on the inlet and exhaust valves, the inlet and outlet air volume of the cage box can be adjusted to make the pressure difference of the cage box on the entire cage frame uniform (pressure difference error ≤3Pa）

Cage frame usedMade of welded 304 stainless steel pipes, it has the advantages of beautiful appearance, firm and stable stability, and easy movement

3. polysulfonePC plastic cage box

specifications470 × 315 × 260mm, equipped with 400ml transparent drinking water bottle;

polycarbonatePC plastic cage box, transparent color, good acid and alkali resistance, and chemical resistance; High temperature resistance 121℃30minHigh temperature and high pressure sterilization, 50 times of high pressure sterilization without deformation; Silicone sealing strips can be sterilized under high pressure simultaneously; Stainless steel mesh cover: The steel wire material is 1Cr18Ni9Ti.

The upper and upper exhaust structure of the cage box static pressure box terminal filtration system has the advantages of safety, efficiency, low flow rate, and practicality.

The outlet of the static pressure box is equipped with a high-efficiency filtration membrane, which filters the air entering the cage through three layers (coarse filtration inside the main unit)HEPA high-efficiency cage terminal filtration membrane can prevent contamination of pipelines or connections.

The staggered position of the air supply and exhaust vents can prevent air flow short circuits inside the cage box (without dead corners) and improve filtration efficiency; At the same time, the weak airflow inside the cage has minimal impact on animals, ensuring that they grow and develop in a comfortable, quiet, and clean environment.

The air outlet of the cage box is equipped with a filter membrane, which can prevent cushion dust from blowing into the pipeline and ensure the smooth operation of the cage frame exhaust system.

The top of the cage box is equipped with a vital ventilation window, which can prevent animals from suffocating due to power outages; Plug in record card for easy experiment management.
