In today’s environment, transportation agencies are increasingly focused on reducing the risk posed by pollutants and airborne contaminants to deliver the safest environments for their customers. Thermo King’s return air filters provide the maximum protection for both riders and the HVAC equipment. Our filters prevent particulate accumulation on evaporator coils resulting in reduced road calls from HVAC system failures.
Thermo King offers three air filters in several filtering efficiencies with different contaminant holding capacities.
What MERV rating means in air filtration
A clear strategy to mitigate in-cabin contaminant exposure to passengers and reduce HVAC maintenance costs is to use a quality filter with a high Minimum Efficiency Reporting Value (MERV) and efficiency rating.
A filter with a higher rating is more effective at filtering out contaminants and small particles.
Merv Rating Levels
Between 1-4
- Captures: less than 20% of particles between 3-10 microns in size
- Including: dust mites and pollen
Between 5-8
- Captures: 20% - 70% of particles between 3-10 microns in size less than 20% of particles between 1-3 microns in size
- Including: mold spores and cement dust
All three air filters meet the standard set forth by the Federal Motor Vehicle Safety Standard 302 (49 CFR 571.302) and American Society of Heating, Refrigerating and Air-Conditioning Engineers Standard 52.2-2007. They are also disposable.
低效过滤器如何影响你的利润
非原厂滤网会对Thermo King系统的可靠性产生许多后续影响。随着时间推移，这可能会让你的系统比实际需要的更辛苦，导致系统组件早期故障。
其他陷阱：
- 在暖通空调系统中使用限制气流的过滤器会导致冷却能力下降，并有可能发生蒸发器盘管结冰。
- 低MERV和松散滤清器允许空气旁通，并需要额外的预防性维护程序，如线圈清洁。
- 脏蒸发器线圈会降低冷却能力并降低系统效率。
