Extraction Booth Airflow Testing
Proper airflow is critical in a C1D1 extraction booth. Insufficient ventilation allows flammable vapor accumulation. WERCS measures and documents airflow performance including CFM, negative pressure differential, and purge system response - providing the evidence inspectors and insurers require.
Problems We Solve
WERCS technicians are experts at diagnosing and fixing extraction booth issues that cost you time and money.
Insufficient Exhaust
Extraction booths require 1,500-10,000+ CFM depending on size and municipal code. Undersized or degraded exhaust systems allow vapor accumulation above safe...
Lost Negative Pressure
Extraction rooms must maintain net negative interior pressure (typically -0.02 w.c.) to prevent vapor escape.
Purge System Failure
When gas sensors detect elevated LEL, ventilation must ramp from base rate to purge rate. If the purge system fails to activate or transition properly,...
No Documented Baseline
Without documented airflow performance data, you cannot prove your system meets code requirements or detect degradation over time.
Our Service Process
How WERCS delivers exceptional results every time
Face Velocity Measurement
We measure air velocity across the booth opening to verify adequate capture velocity for vapor containment.
Exhaust Volume Testing
Using calibrated instruments, we measure total exhaust CFM and compare to design specifications and code requirements.
Negative Pressure Verification
We measure differential pressure between the extraction room and adjacent spaces to verify net negative pressure is maintained.
Purge System Test
We trigger the gas detection interlock and verify the ventilation system transitions from base rate to purge rate within specified time.
Equipment We Service
WERCS technicians are trained on all major extraction booth brands and models.
