300dd ec forward curved roof exhauster.
Roof curved forward.
These roofs are architecturally sound and visually pleasant looking.
Double width forward curved centrifugal wheel results in high efficiency and low sound levels.
A roof with the pitch divided into a shallow slope above a steeper slope.
Sizes wheel diameters 7 5 to 36 5 inches 195 mm to 930 mm performance airflow to 29 100 cfm 49 400 m 3 hour.
Blower is mounted on heavy steel angle with rubber isolators.
If you have a resort or beautiful villa you can opt for a curved roof.
Forward curved blades provide a low noise level and relatively small air flow with a high increase in static pressure.
Cabinet insulated with 1 2 fiberglass insulation.
Square base allows discharge to be oriented in any of 4 directions.
Stable performance down to 700 cfm 1189 m3 hr.
A roof similar to a mansard but sloped in one direction rather than both.
You can paint these roofs in bright and contrasting shades.
Smaller blowers may have backward inclined blades which are straight not curved.
Applications include hvac ventilation oven and dryer exhaust and process drying and cooling.
Low operating rpm of forward curved blowers results in low noise levels.
When tight bend radii are specified edge ripple on the roof sheets might prevail.
Permanent washable aluminum filters result in.
Wg 498 pa and up to 14 300 cfm 24 300 m3 hr.
The minimum radius for curving on 0 58mm isq300 material is 900mm and on 0 80mm isq230 material it is 600mm.
When only a part of the sheet is curved and bullnose slight crease marks on the sheets can be expected.
High efficiency direct drive motor for energy efficient low maintenance applications.

The steep slope may be curved.
Backward curved blades as in figure 3 b curve against the direction of the fan wheel s rotation.
Durability for filtered roof supply applications.
Cabinet insulated with 1 2 fiberglass insulation.
Vertical seam panels unless hand formed or customer curved do not work real well on concave or convex surfaces.
Centrifugal fans blowers with forward curved wheels are well suited to ventilation and industrial process applications where moderate capacities at low pressures are required.
Larger backward inclined curved blowers have blades whose backward curvatures mimic that of an airfoil cross section but both designs provide good operating efficiency with.
Attractive green baked powder coat finish.
