WALKER medical vacuum sterilizing filter

The alpha series medical vacuum sterilizing filter is specially designed to protect the equipment from liquids, solid particles and bacterial contamination.

The diameter of the interface is from 1/4 inch to 3 inch, and the screw shell is made of cast aluminum alloy material, and Walker e-coat technology is used for anti-corrosion treatment.Intelligent, modular design ensures optimal flow, ease of installation and multiple coupling characteristics.DN80 - DN150 flanges are welded by carbon steel and have polyester protective coatings.

The design is intelligent, unique and modular

The intelligent filter core design is prefiltered by the hydrophobic borosilicate medium and the open reticular foam.Through unique material structure, energy efficiency is improved, and reliable filtration is realized to minimize pressure drop.

Custom filter medium for optimum efficiency

The unique drop-fit filter has the function of preventing shock, improving stability and improving drainage.Designed for en286-1 and compatible with PED (97/23 / EC) and SPVD (87/404 / EEC).

More than the standard of UK health technology memos 02-01 (HT M 02-01)

Application range includes: hospital dentistry;Internal medicine;Veterinarians, medical devices, etc

Technical note

1. The air flow direction is through the filter element from the outside.

2. Mechanical indicator (65dpuga-250) matching model A028MV to A058MV as the standard.The differential pressure gauge (65DPG250G) matched the model A059MV to A390MV as the standard.The differential gauge applies to all flange connection models.

3. Manual drain valve (MDV25) applies to all models.The sterilized glass exhaust water bottle is standard, and 100 ml is suitable for the model A028MV to A078MV, which is suitable for the model A079MV to A390MV. The additional 1/2 inch feeding side drain is included in the model A391MV to A686MV.

4. The flow above is the free air flow under one bar.

5. The pressure of the side leakage test must be limited to 7 millibar, and only the drain valve and drain valve have been removed.

6. Threads and double helix filters are made of cast aluminum alloy and are compatible with flammable gases with standard PED 97/23 / EC.

7. If supply is available in North America, the corresponding standard iso7/1 of thread connection is called Rp (BSP parallelism), or corresponding to ANSI B2.1 is the NPT.Flange connector is fully matched with BS4504, PN16.

8. Add suffix N to NPT connector.For example: A038MVN.

9. Flange filters are cast in carbon steel.

The flanges are designed and cast in standard BS EN286 and meet the simple pressure vessel requirements.

11. Tolerance error of cross port dimensions of flanged vessels is controlled within the range of plus or minus 3mm, and the vertical error is 1 degree.

12, every 6 months or 1000 hours, the filter cartridge should be replaced (subject to the deadline).
