ASTM F2299/Mask Particle Filtration Efficiency (PFE) Tester

Application

The respiratory resistance tester is suitable for determining the inhalation resistance and exhalation resistance under the regulations of respirators and masks, and for the related testing and inspection of ordinary mask products by the national labor protection equipment inspection agency manufacturer.

Standards

GB2626-2006, GB / T32610-2016

It is used to test the percentage of materials containing bacteria suspended particles at the specified flow rate.

For disinfection of large spaces. Removable aerosol disinfection and sterilization equipment, manual and automatic control, timing and quantitative spraying, adjustable spray volume Suitable for hospitals, campuses, stations, airports, and other large public places.

Under the action of compressed air, the medicinal solution is spouted from the nozzle to form aerosol ions of 2 to 10 μm, which quickly and fully integrates in the ambient air; kills pathogenic microorganisms in the air, and realizes a full range of dead space-free disinfection of the environmental space. Sterile environment. The sterilized objects will not form dew condensation and form droplets.

Face Mask Flame Retardant Tester. It is a special test instrument for the flame retardancy of a mask. Mask testing machines for surgical face masks, N95 masks, Melt-blown fabric.

Medical Mask Exhalation Valve Air Tightness Tester  is Used to detect the air tightness of the mask breath valve. GBPI offers mask testing machines for surgical face masks, N95 masks, Melt-blown fabric. BFE Tester, PFE Tester, N95 Tester, Melt-blown fabric Tester

GBPI offers mask testing machines for surgical face masks, N95 masks, Melt-blown fabric. BFE Tester, PFE Tester, N95 Tester, Melt-blown fabric Tester

GC9802-K Face Mask Ethylene Oxide (EO) Residuals Testing Gas Chromatography has a reasonable structure, stable and reliable performance, simple operation and convenient maintenance. Can be widely used in petroleum, chemical industry, pesticides, medicine and health, commodity inspection, environmental protection, universities and other production and scientific research departments. It can be used to detect ethylene oxide and other organic solvents. Detects purity or content of a single solvent

It is suitable for the resistance of the mask to the penetration of synthetic blood under different levels of test pressure. The mask material is tested with synthetic blood under continuously applied pressure, and the penetration of synthetic blood on the material is visually checked.

To test the tensile strength, peeling strength, heat sealing strength, tearing strength, piercing strength of plastic film, composite film, tape, soft packaging material, rubber sheets, paper, non-woven fabrics and other packaging materials

Used for face mask air flow resistance and differential pressure testing to check breathability and can also be used to check differential pressure of textile materials gas exchanger.

Application

It is to test the filtering efficiency of particulate protective masks and medical masks and to determine the resistance of ordinary fabrics and medical protective masks to the constant flow of airflow.

Standards

GB2626, NIOSH 42 CFR Part 84, EN143, EN149, JIS/T 8151
