Industrial Rooftop Mounted Exhaust Fans
Slope type
The slope-type roof-mounted fan on the homepage is described as engineered for powerful ventilation and long-term outdoor exposure, with a waterproof dome-shaped cap, a wind deflector, and six axial blades. Its modular design is described as allowing easier maintenance and installation, and its reinforced structure as withstanding harsh weather and humidity. Suitable spaces named on the homepage are factories, poultry houses, greenhouses, and warehouse facilities in Southeast Asia's climate. No airflow, power, or size figure is stated for this model in the source material, so none is stated here — confirm those figures for the size you need.
Elbow type
The elbow-type roof-mounted fan is described on the homepage as a fibreglass exhaust fan that blows air through its blades so the indoor environment forms a negative pressure environment, exhausting air while introducing fresh air. It is described as lightweight, easy to install, and low in energy consumption with excellent airflow capacity, with a smooth-surfaced FRP housing that is UV and weather resistant for indoor and outdoor applications. Again, no numeric specification was verified for this model, so the page does not invent one.
Choosing between roof and wall mounting
Roof mounting suits spaces where wall area is taken by doors, pads, or equipment, or where the roof is the shortest path for hot air to leave. Wall-mounted negative pressure fans suit pad-and-fan layouts where air must travel the full length of the space. If you are unsure, send a plan of the space with wall and roof openings marked, and ask which mounting the supplier recommends for that layout.
Before ordering, confirm: the exact model and voltage for your site, the airflow and size you need, MOQ, lead time, and warranty. This page lists only what the source material verifies; anything not listed here is a question to ask, not a specification to assume.
This page covers two listed models without a verified specification table, so it states no airflow, power, or size figures — confirm those figures for the size you need.
Request a ventilation and cooling layout
Send your space size, heat source, and voltage, and ask for a layout using the equipment families on this page. Before payment, confirm MOQ, lead time, voltage, and warranty for your order.
