Here's something most lab designers overlook: more than half of all laboratory work happens on open benches, not inside fume hoods. Weighing, solution prep, sample transfer — these routine tasks generate low-level fumes that drift right through the operator's breathing zone. Turkish OHS regulations under the TSE framework require employers to minimize chemical exposure, but nobody's installing a fume hood for every weighing operation.

Desktop Exhaust Ports on Full Steel Lab Benches

HJSLab builds slot-style exhaust ports into the rear edge of our full steel lab bench surface. Connected to the lab's existing ductwork through a DN150 branch line, these ports create a gentle airflow from front to back across the worktop — pulling fumes away from the operator before they reach face height.

Face velocity is calibrated between 0.3-0.5 m/s. Below 0.3 and the exhaust doesn't catch volatile vapors effectively. Above 0.5 and lightweight items — filter paper, powder samples — start getting pulled toward the slot. The exhaust grille uses 316L stainless steel to handle corrosive fume exposure, and it's removable for periodic cleaning.

Sharing Ductwork with Fume Hoods

No need for a separate exhaust system. HJSLab's approach ties the desktop exhaust into existing fume hood ductwork through a motorized damper. When both the bench exhaust and fume hood operate simultaneously, our variable-frequency drive controller increases fan speed automatically. A duct pressure sensor monitors real-time negative pressure — if it drops, an alarm triggers before air quality is compromised.

Why Chinese Manufacturing Delivers Better Value

A comparable desktop exhaust integration from European lab furniture brands costs substantially more than HJSLab's solution — and uses the same engineering principles. Our Suzhou factory runs ISO 9001 certified production with Chinese manufacturing cost advantages: competitive raw material pricing, skilled welding technicians, and integrated supply chains.

Turkey's position on the Belt and Road corridor gives HJSLab efficient logistics options — sea freight through Mersin or Istanbul ports takes approximately 20-25 days. Our team assists with TSE compliance documentation.

For laboratories in Istanbul, Ankara, Izmir, or Antalya looking to improve operator air quality without the expense of additional fume hoods, HJSLab's desktop exhaust solution fits the bill. Contact us for a ventilation integration assessment.
