Frame
Styles
 |
SR2400 Design applications where the ductwork flanges are present and a complete frame assembly is preferred. This style works well for high temperature applications. |
|
| Complete drop-in assembly | ||
| Prefabricated standard frames reduce cost | ||
| Belting hardware accessible from outside | ||
| Best choice when adjacent structures or equipment cannot permit liner protrusion beyond attachment flange | ||
| Accepts shop welded flow liner | ||
| Readily accepts eared pillow design | ||
| Used to fill large breech openings | ||
| Accommodates large lateral movements | ||
| Provides proper setback for belt protection | ||
 |
SR2500 Complete drop-in assembly design which works well with low to moderate temperature applications with low levels of particulate accumulation. | |
| Economic frame using standard angle sizes | ||
| Accessibility to bolting hardware | ||
| Accepts shop welded flow liner | ||
| Designed for internal (SR2550) or external belt replacement (SR2500) | ||
| Used frequently with fan applications | ||
| Studs or tack welded nuts are optional on belt flange | ||
 |
SR2600 Similar to the SR2500 style and is used where additional standoff is necessary or preferred. This design works well in low to moderate temperature applications with low levels of particulate accumulation. | |
| Economic frame using standard angle sizes | ||
| Fabric wrap design used to retrofit over existing metal expansion joints (possible on-line installation) | ||
| Complete assembly drop-in design | ||
| Designed for internal (SR2650) or external belt replacement (SR2500) | ||
| Used frequently with fan applications | ||
| Accepts shop welded flow liner | ||
| Studs or tack welded nuts are optional on belt flange | ||
 |
SR2700 Used for low-to-high temperature applications with a cavity pillow, where high levels of particulate are present. | |
| Accommodates both flanged and non-flanged ductwork | ||
| “Z” style with integral telescoping flow liners | ||
| Reduces particulate accumulation in frame cavity | ||
| Provides protection for belts and pillows | ||
| Complete accessibility to bolting hardware | ||
| Accepts eared pillow design | ||
| Accommodates large lateral movements | ||
| Tack welded nuts are optional | ||
| Provides proper setback for belt protection | ||
 |
SR2750 Similar to SR2700 with the exception of a single integral flow liner. This design works well with lower particulate levels or vertical duct applications. | |
| Accommodates both flanged and non-flanged ductwork | ||
| “Z” style integral upstream flow liner | ||
| Provides protection for belts and pillows | ||
| Complete accessibility to bolting hardware | ||
| Accommodates large lateral movements | ||
| Tack welded nuts are optional | ||
| Provides proper setback for belt protection | ||
 |
SR2800 This style frame is well suited for installation with field assembly over existing expansion joints, and is utilized for all temperature ratings. | |
| Economic frame utilizing standard prefabricated angle iron | ||
| Either welded or bolted frame can be utilized | ||
| Fabric wrap design can be used to retrofit over existing metal expansion joints (possible on-line installation) | ||
| Accepts eared pillow design | ||
| Facilitates field assembly and fit-up | ||
| Tack welded nuts are optional | ||
| Provides proper setback for belt protection | ||
 |
SR2900 Best utilized where flanges are not present and field assembly is required or preferred. | |
| Fabric wrap design used over existing metal expansion joints (possible on-line installation) | ||
| Provides additional stiffener reinforcement to existing ductwork | ||
| Utilizes standard structural steel channels for economical design | ||
| Flanges act as duct stiffeners | ||
 |
U1000 The standard integrally flanged U-belt design is used for low to moderate temperatures applications where duct flanges are present and particulate loading is minimal | |
| Lowest initial cost due to reduced metal frame and fasteners cost | ||
| Molded corners provided for rectangular ductwork | ||
| Accommodates flanged ducting or equipment and utilized frequently for fan applications | ||
| Minimal shipping costs | ||
| Standard 3” (75mm) high flange design | ||
 |
SLEEVES Sleeves are primarily used for vibration in H.V.A.C. applications with minimal pressures. | |
| Least expensive design | ||
| Supplied endless or open ended for field-wrap of pipe penetration applications | ||
| Supplied with worm gear band clamps | ||
| For vibration applications | ||
| Provided with gaskets for Teflon® belt material | ||
