New filter standard ISO 16890

Why develop a new filter standard?

  • Filter efficiency and classification are now more in accordance with reality
  • Same standard across the globe ⇔ no confusion
  • The standard entered into force on 1 July 2018

EXHAUSTO has chosen to retain the old article numbers, but uses the new filter designations in article texts. etc.

How a filter class is determined in accordance with the new standard

New filter standard ISO 16890 – compared to EN 13779

  • Test is based on particle size 0,3–10 μm 
  • Classification is based on the result for the particle sizes PM1, PM2,5 och PM10
  • Static electricity in the filter is discharged during the test
  • Dust load with ISO "fine dust" to find pressure drop

Prefiltration

Future filter choice in consideration of the actual outdoor climate and desired indoor climate.

According to ISO 16798, the choice of filter class must be based on the outdoor air quality (ODA) and the desired quality of the supply air (SUP):

 

EXHAUSTO therefore provides prefiltration on VEX200, VEX300T and VEX4000.

Outdoor air quality SUP1
(High)
PM2,5 ≤ 2,5 
PM10 ≤ 5
SUP2
(Medium)
PM2,5 ≤ 5 
PM10 ≤ 10
SUP3
(Moderate)
PM2,5 ≤ 7,5 
PM10 ≤ 15
SUP4
(Low)
PM2,5 ≤ 10 
PM10 ≤  20
SUP5
(Very low)

PM10 ≤ 30

EXHAUSTO tilbyder derfor for-filtrering på VEX300T, VEX200 og VEX4000.
