Installing actuators onto jackshafts can be a hassle. If the actuator linkage is not exact for the type of equipment you are mounting your damper actuator on to, it is up to the installer to figure out how to make it work.
Belimo USA has come up with an awesome new jackshaft assembly that makes installing a damper actuator a snap.
The Belimo ZG-JSL linkage simplifies typical installations and eliminates the difficulties where jackshaft bearings are hard to access. The Belimo ZG-JSL linkage has a built-in shaft which Read More
A key part of the life safety system in any building is the fire and smoke dampers. When working as designed these dampers help prevent the spread of fire and smoke throughout the building in the event of a fire. The fire dampers usually do not have control actuators and close when a rise in temperature to about 165 degrees causes a fusible link to open, causing the fire damper to close and stop the fire from passing through a barrier. Smoke dampers and combination dampers do have actuators like those made by Belimo.
These smoke and fire damper actuators become an important maintenance consideration because failure to
Belimo is offering a really cool new linkage the Belimo ZG- JSL Belimo has created the quickest install designed with ease in mind. The ZG-JSL linkage is designed to facilitate the attachment of select Belimo actuators to a damper’s jackshaft. The unique open ended design allows the linkage to clamp on to any part of a jackshaft measuring from 1/2″ to 1.05″ in diameter.Saves time and cost
The Belimo ZG-JSL linkage simplifies typical installations and eliminates the difficulties where jackshaft bearings are hard to access. By improving the method of installing actuators onto jackshafts, the installer saves on installation time translating into a cost savings. The quicker the install, the sooner the installer can move on to the next project. Now with the Belimo ZG-JSL linkage all jackshaft installations will only take minutes!Ideal for tight spaces Read More
Choosing dampers can be a mind boggling experience, but once you have an understanding of the basics and a few well asked questions, your needs can be quickly and expertly filled using Honeywell Commercial Dampers.
The first Honeywell Commercial Damper we will look at is the D series of rectangular dampers. The D series is broken down into 3 types the D1, the D2, and, you guessed it, the D3 series. Here are the basics.
D1… ultra low leakage design based at 6cfm @ 4”wc with a velocity rating of 2500-4000 fpm. The blade seals are silicone and the jamb seals are 304 stainless steel.
D2…low leakage design based at 10cfm @ 4”wc with a velocity rating of 2000-3000fpm. The blade seals are extruded vinyl and the jamb seals are 304 stainless steel.
D3…low leakage design based at 120cfm @4”wc with a velocity rating of 2000-3000fpm. These dampers do not have blade seals or jamb seals.
All the rectangular dampers can be fully optioned and sized depending on the client’s needs.
Competitive comparisons:
D1…Ruskin CD60 and the Greenheck VCD33
D2…Ruskin CD36/46
D3…Ruskin CD35 and the Greenheck VCD20
Note: Actuators for the rectangular dampers can be sized by knowing the proper torque needs for the actuator. The formula is: damper size (length X width) X rated torque multiplier X safety factor = Actuator in-lb torque requirements.
Commercial Round Dampers from Honeywell are available from 6” to 16” with or without actuators.
The D690 series is without actuator, and the DM7600 series come mounted with a Honeywell actuator with a 90 second timing and a 2-10 Vdc or 4-20 mA ( Honeywell ML7161) or SPDT Floating (Honeywell ML6161) series actuator.
