Centrifugal High Plume Dilution Laboratory Exhaust Fan

The 110mm Automatic Roof Ventilator is a highly durable, premium chimney hood and exhaust fan designed to rapidly release trapped air and improve indoor air quality. Engineered for both residential and light commercial applications, this ventilator operates automatically to provide continuous, highly effective airflow while preventing wind intrusion and air stagnation. Operating at an ultra-quiet 45 decibels, it ensures a peaceful indoor environment without the disruptive noise of traditional industrial fans. Constructed from heavy-duty, polished stainless steel, this ventilator is built to withstand extreme environmental conditions. It is completely rustproof and highly resistant to high temperatures, acid, and alkali erosion, making it exceptionally reliable even in harsh weather. The intelligent design ensures it remains fully functional and unaffected by heavy rain. With an easy pipe-mount installation process and all necessary mounting brackets and screws included, upgrading your property's ventilation system is straightforward and efficient.

Durable Roof-Mounted Protection for HVAC Systems These heavy-duty weather caps from PennBarry provide reliable, roof-mounted protection for both air intake and exhaust ventilation systems. Constructed entirely from premium spun aluminum - including the cap, airshaft, and mounting base - they are engineered to withstand harsh environmental conditions while maintaining optimal, unrestricted airflow. To protect your facility's ductwork and interior, the integrated airshaft features a built-in birdscreen, effectively preventing wildlife and large debris from entering the system. The product line is divided into two versatile configurations to suit your project needs: the WCF series (flush mount, standard throat matching) and the WCC series (which allows for the installation of roof dampers and requires a 12" high curb for motorized options)

Reliable, Energy-Free Roof Ventilation for Mid-Sized Facilities This 18-inch Wind-Driven Turbine Exhaust Ventilator provides continuous, energy-free roof ventilation for commercial and industrial buildings. It is built with a sturdy steel housing that features a galvanized finish for enhanced durability and corrosion resistance. Delivering a robust 1,200 cfm of airflow at wind speeds as low as 4 mph, it efficiently extracts hot, stale air from your facility. The unit operates on a highly efficient bearing system featuring an oiless bronze upper bearing and a lower thrust-type ball bearing. To ensure maximum stability in harsh weather conditions, it is structurally reinforced with external steel bracing.

This compact Wind-Driven Turbine Exhaust Ventilator provides continuous, energy-free ventilation for smaller enclosures, sheds, and targeted roof sections. Built with a rugged steel housing featuring a galvanized finish, it is designed to resist corrosion and withstand harsh outdoor elements. Despite its smaller 6-inch throat diameter, it efficiently extracts air, delivering 147 cfm of airflow at wind speeds as low as 4 mph. The unit is structurally reinforced with external aluminum bracing. For smooth, frictionless rotation, it relies on an advanced bearing system comprising a lower thrust-type ball bearing and an oil-less bronze upper bearing.
