Inspection standards for medical masks

Medical protective mask

It complies with the GB19083-2003 “Technical Requirements for Medical Protective Masks” standard. Important technical indicators include non-oily particle filtration efficiency and airflow resistance: (1) Filtration efficiency: Under the condition of air flow (85±2) L/min, the aerodynamics The filtration efficiency of sodium chloride aerosol with a median diameter of (0.24±0.06)μm is not less than 95%, which is in line with N95 (or FFP2) and above. (2) Inspiratory resistance: Under the above flow conditions, the inspiratory resistance does not exceed 343.2Pa (35mmH2O).

Medical surgical masks

In line with the YY 0469-2004 “Technical Requirements for Medical Surgical Masks” standard, important technical indicators include filtration efficiency, bacterial filtration efficiency and respiratory resistance: (1) Filtration efficiency: under the condition of air flow (30 ± 2) L/min, The filtration efficiency of sodium chloride aerosol with kinetic median diameter (0.24±0.06)μm is not less than 30% (2) Bacterial filtration efficiency: under the specified conditions, the average particle diameter is (3±0.3)μm golden yellow The filtration efficiency of staphylococcal aerosol is not less than 95%; (3) Respiratory resistance: Under the condition of filtration efficiency and flow rate, the inhalation resistance does not exceed 49Pa and the exhalation resistance does not exceed 29.4Pa.
3. Ordinary medical masks
Comply with the relevant registered product standards (YZB), generally lack the filtration efficiency requirements for particles and bacteria, or the filtration efficiency requirements for particles and bacteria are lower than medical surgical masks and medical protective masks.

About Us

Before Gator Track factory, we are AIMAX, trader for rubber tracks for over 15 years. Drawing from our experience in this field, to better serve our customers, we felt the urge to build a factory of our own, not in pursuit of quantity we can sell, but of each good track we built and make it count.

In 2015, Gator Track was founded with the help of rich experienced engineers. Our first track was built on 8th, March, 2016.  For the total built 50 containers in 2016, so far only 1 claim for 1 pc.

As a brand new factory, we have all brand new toolings for most of the sizes for excavator tracks, loader tracks, dumper tracks, ASV tracks and rubber pads. Most recently we’ve added a new production line for snow mobile tracks and robot tracks. Through tear and sweat, happy to see we are growing.

We look forward to the opportunity to earn your business and a long, lasting relationship.
