Model RV Romlair Ridge Ventilators are ideal for steel buildings and other applications requiring an inconspicuous high volume exhaust vent. Install on peaks, flat roofs, or on curbs.
A wide range of sizes are available from 4” up 60”. Standard 9” & 12” RV units come complete with end caps and a worm operator and can be used for single unit installations or a continuous run. No special join plates or operators are required on these two sizes for a continuous run. This allows stocking of only one type of ventilator to fit all needs. All other sizes come in the standard single unit design or continuous run design.
