Range Ventilation Certification

Existing Ranges

Range Ventilation Design, Inc. offers the following Technical Consultation services:

Range Ventilation Certification service including: Perform range ventilation system airside test & balance. Verify (adjust/calibrate if applicable) the range ventilation controls/equipment are maintaining a constant negative pressure within the firing range while operational. Examine and recommend, if applicable, corrective operations and procedures. Verify and adjust laminar airflow distribution system to provide laminar airflow (as best as possible given laminar airflow distribution system type, range architectural considerations, distance from back wall to firing line and range ventilation system design in general) and measure laminar airflow by taking three (3) measurements at each of the following elevations above the finished floor, 1’-0”, 2’-6”, 4’-0”, 5’-6” and 7’-0” per shooting position (15 total measurements). The adjustments and measurements should target the following criteria:

  • Average velocity over all shooting positions: 70 to 80 fpm
  • Average velocity over each shooting position: 50 to 100 fpm
  • All velocity measurements shall travel downrange: >0
