Ruskin model DFD-LP Low Profile, Low Pressure Drop Dynamic Fire Damper is designed for dual directional air flow. The damper is constructed with an integral sleeve/frame and an aerodynamic shaped blade for high-velocity applications.
Larson Electronics has released a 24-in explosion proof ventilation fan ideal for areas where flammable gases, vapors, or finely pulverized dusts may exist. The EPF-HPSM-24-480V high-pressure explosion proof ventilation fan from Larson Electronics features three spark resistant cast aluminum blades that move stale air at a rate of up to 6,860 cubic ft per minute. The frame is made of heavy duty 14-gauge steel that is completely arc welded with tubular supports. This unit is rated for use in Class 1 Group D and Class II Groups F and G hazardous areas.
Greenheck’s new Model EVH-501D stationary vertical blade louver is Florida Building Code Approved for use in the High Velocity Hurricane Zone and Miami-Dade Approved for use where the room behind the louver is not designed to drain water penetrating into the room or the room will house non-water resistant or water proof equipment, components, or supplies.
Greenheck has expanded its collection non-actuated fire dampers in the marketplace. Now available in widths as great as 144 in and heights up to 100 in, the company says the Model DFDAF-310 represents a 20% dimensional increase over dampers previously available for a 1.5-hour dynamically-rated fire damper with airfoil blade construction.
Pottorff has announced the addition of the ECV-645-MD 6-in deep, vertical blade louver to its Miami-Dade approved product line-up. The ECV-645-MD is AMCA rated for Air Performance and Wind-Driven Rain and is approved by the Florida Building Code.
Continental Fan says its FADP Fiberglass Panel Fans provide aerodynamically superior performance in a direct drive design. The FADP fan is ideal for corrosive environments or contaminated air stream applications.
Greenheck’s new Model AFJ-601D stationary acoustic louver is Florida Building Code approved and Miami-Dade qualified for use in the Wind-Borne Debris Zone. Featuring a 6-in deep J blade, the AFJ-601D is designed to restrict the transmission of high and low frequency sounds generated by mechanical equipment and to act as an exterior weather louver.
Pottorff is has introduced its new EXA-645 combination louver. The company says it is a high-performance louver with Best-In-Class AMCA certified performance for free area (50.4%) and a pressure loss of 0.15 in. wg. @1,272 fpm (6.46 m/s). The EXA-645 features stationary drainable louver blades that protect against water penetration along with an integral airfoil blade control damper which will allow for positive shutoff protection from air intake and exhaust openings.
Greenheck introduced the Model AFL-501, a 5.5-in deep, severe duty aluminum louver that protects exterior wall penetrations on FEMA 361 or 320 compliant storm shelters or safe rooms. According to the company, the Model AFL-501’s design incorporates inverted V-style blades that lend high free area, excellent resistance to water penetration and very low airflow resistance, while providing maximum protection against extremely high wind loads and wind-borne debris.
