Vertical Laminar Downflow Clean Air Workstations

Teknopak offers Vertical Laminar Downflow Bioclean Workstations in three versions, all conforming to current ISO/TC standards and guidelines. Employing contemporary technologies in microcontamination control, these systems cleandown your critical workspace and sustain design conditions through effective removal of work generated contaminants.

The first is the popular straddle version with integral work table; the second is the stand mounted version which abounds in the parenteral and wafer fab industries. The last is a slimmer version of the second, preferred in rooms with low ceiling height.

Special models are available for wet chemical processing work involving photolithography: the standard version, and the deluxe which features, among other things, a built-in storage cabinet.

All Teknopak units bear the hallmark of committed professionalism, and promise you quality, security, protection and full-value-for-money. Backed by rich experience, continuing research and strong infrastructure, Teknopak’s cost-performance-benefit equations remain unequaled.

Choose Teknopak; and you can be sure you are investing in the best in the market.
