About us

Founded in 2013, Air-Lab s.r.o. has been an accredited testing laboratory for fans and HVAC equipment in keeping with international standards EN ISO/IEC 17025 since 2014.

The quality and transferability of the results is achieved due to the top technical equipment (Ahlborn, Brüel & Kjær, Endress+Hauser, MATTECH, Rosemount, Vaisala) and it is based on responsible work of qualified test technicians. Professional development and enhancing the testing procedures is an integral part of the activities of our accredited laboratory.

Through performed measurements and delivered results, we are a partner for our customers in research, development and improvement of their products, and we provide them with sources for marketing and launching their products on the market.

We complete measuring:

  • air characteristics of fans (air flow rate × pressure characteristics)
  • pressure drop rates of HVAC elements
  • thermal and humidity efficiency rates of heat recovery exchangers (stand-alone and built-in in AHUs)
  • power consumption
  • noise levels (various noise sources, also outside of the HVAC field)
  • deformation of housings of AHUs due to excessive overpressure and underpressure
  • heat transfer and heat leak through housings, thermal bridges

We provide our customers:

  • accurate accredited (as per the respective standards) and non-accredited (as required by the client) measuring of all relevant quantities in the HVAC field
  • preparation and issue of test reports in Czech or English - accredited reports valid in ILAC-MRA treaty signatory countries (104 global economies)
  • measurements and reports required for applying for field-related and specialized certificates (Passive House Institute, VDI 6022, DIBt…)
