Zefon Pumps and Accessories

Air quality technicians, industrial hygienists, and occupational safety personnel working in the field need access to sophisticated and reliable pumps that are also easy to use and portable. Pumps play a critical role in the sample collection and analysis process. Depending on the application, they may be used for IAQ analysis, personal abatement, industrial hygiene, and other important tasks. When paired with the appropriate filter media, they offer a convenient way to collect and test for exposure to asbestos, lead, silica, beryllium, respirable dust, hazardous particulates, and mold spores.

As a longstanding partner to air quality technicians, we have several area, IAQ and personal air sampling pumps for sale in our online store. We design and manufacture several brands of pumps in-house, taking into account the needs of today's working professionals, to create pumps that integrate seamlessly into your workflow.
