316 Stainless Steel Positive Pressure Filter
Product Overview
The stainless steel barrel-type pressure filter is a precision solid-liquid separation and sterilization filtering device. It is used for purification and sterilization filtration of liquids, especially for sterilization filtration of culture media, filtration of protein solution, and industrial decarbonization filtration. The filter is suitable for the fields of scientific research, medical treatment, chemical industry, food, beverage, electronic machinery and so on.

Precaution

1. Before filtering, fully moisten the filter membrane to ensure effective filtering.

2. Do not directly touch the filtering surface of the filter membrane with hands to avoid pollution.

3. Do not exceed the pressure range of the film membrane during operation.

4. Gently operate the ball valves during filtering to avoid damage to the ball valves.

5. After filtering, do not scrape the stainless steel inner wall with sharp tools.

6. Do not open the hoops or remove parts during filtering.

7. Wear protective gloves and goggles during operation.

Note: There is no air pump included in the packing list. Customers should use their own air pumps or air compressors.

Product Features & Advantages
Pressure Gauge
Pressure Gauge
The precision pressure gauge adopts double-scale display, allows the operator to quickly read the pressure value. It can accurately show the pressure change, ensuring the sample separation effect is stable and reliable.
Solution Inlet
Solution Inlet
The solution inlet adopts the hoop design, can be easily opened and closed, greatly reduces the solution feeding time, effectively avoids liquid leakage and ensures the filtering process is stable and safe.
Ball Valve
Ball Valve
The ball valve is simple in structure, convenient to operate, easy to clean and long in service life. It can quickly achieve air connection and disconnection, is free of air leakage risks and has higher durability and practicability.
Filtering Assembly
Filtering Assembly
Multiple lifting eye bolts are evenly distributed on the flange plate to achieve even tightening and form high-strength annular sealing, assembly and disassembly are convenient and quick, and the filter net can be effectively fixed.
Liquid Outlet
Liquid Outlet
The liquid outlet is of a detachable structure, so cleaning and maintenance are convenient and effortless. Liquid can smoothly flow out of the liquid outlet, and filtrate collection or online sampling can be effectively achieved.
Air Adjusting Valve
Air Adjusting Valve
The air adjusting valve can be used to stably adjust the air pressure, prevents the air pressure fluctuation from affecting the filtering speed and improves the sample separation precision and efficiency.
Operation Method

Loosen the lifting eye bolts, take down the barrel body and install the filter membrane.

Install the barrel body, and tighten the lifting eye bolts to seal the filter membrane.

Take down the hoop and the top ball valve, pour to-be-filtered raw liquid into the liquid inlet.

Install the top ball valve and tighten the hoop to seal the liquid inlet.

Turn on the air pump, and adjust the pressure to the appropriate value as needed.

Slowly open the air inlet valve, and begin filtering the liquid.

After filtering, close the air inlet valve and open the pressure relief valve.

Turn off the air pump, remove the barrel body and take out the filter cake and filtrate.

Clean the machine thoroughly after filtering.
