Regulation and shut-off damper SPB and SPC SPB / SPC -type multi leaf damper is a robust and reliable regulation and shut-off device to be used for different purposes in air handling systems.

Regulation and shut-off damper SPB and SPC Area of application Multi leaf dampers are used as regulation, shut-off and mixing dampers in air handling systems and units. Properties • SPB-1 • SPB-3 • SPB-3L • SPB-3LE • SPB-4L • SPB-4LE regulation damper for balancing air flows - leakage class: 1 (CEN) - leakage class of casing: B regulation and shut-off damper to be used where low leakage is required - leakage class: 3 (CEN) - leakage class of casing: C shut-off damper to be used where low leakage and effective thermal insulation are required - leakage class: 3 (CEN) - leakage class of...

Regulation and shut-off damper SPB and SPC TECHNICAL DATA The difference between widths and heights of available damper sizes is 10 mm. If the face surface is larger than 5 m2, the damper is put together of two or more units. Construction and dimensions are agreed on separately. Dimensions Width B Height H B x H Dampers with flange joints are equipped with Ø5 mm screw holes with 200 mm spacing to enable the mounting e.g. to wall surface without a counterflange. base for motor moottorialusta The multi leaf damper is also available with a protective cover for the lever mechanism. The...

Regulation and shut-off damper SPB and SPC Motor torque TECHNICAL DATA Max. allowable pressure difference 3000 The torque used depends e.g. on the type, width and length of the multi leaf damper, the total length of the sealing surfaces and the mounting method. The motor torque required for the shut-off function of SPB-3 and SPB-4 and the recommended motor type are shown in the tables below. 10 Nm ACTUATOR 20 Nm ACTUATOR 30 Nm ACTUATOR Fläkt Woods Specifications are subject of alteration without further notice

Regulation and shut-off damper SPB and SPC Sound power level LW Face surface area of damper (m2) The sound power levels of the duct for every octave band are obtained by adding the corrections Koct of octave bands and KA of the face surface (see tables above) to the total sound pressure level Lp10A, dB(A), according to the following formula: Medium frequency of octave band (Hz) 63 Sound power level LW in duct when damper closed Correction Koct is the average in the area of application of SPB. Face surface velocity v (m/s) Medium frequency of octave band (Hz) 63 TECHNICAL DATA Face surface...

Regulation and shut-off damper SPB and SPC TECHNICAL DATA SPC-3 • leakage class: 3 (CEN) • leakage class of casing: C • no thermal insulation SPC-3L • leakage class: 3 (CEN) • leakage class of casing: C • blades thermally insulated with mineral wool • heat transmission Um = 4,5 W/m2K Due to its moderate need for space and its excellent mixing performance, SPC is very well suited e.g. for the mixing damper of an air hamdling unit. SPC-3LE • leakage class: 3 (CEN) • leakage class of casing: C • blades and casing thermally insulated with mineral wool (outer dimensions B+120, H+60) • heat...
