Buy Landis Staefa: Damper Actuator Models

With a vast experience in the fields of heating, ventilation, air conditioning and refrigeration (HVACR), Landis Staefa has been a premium manufacturer of parts, providing solutions for home, commercial or industrial applications. Their success on the HVACR control market was exceptional throughout the Company’s 65-year existence and it constantly provided a challenge for Landis Staefa’s engineers and working staff, to produce the best quality, highest reliability parts and components on the market.

The Landis Staefa damper actuator components are no exception, the manufacturer’s models being constantly improved and finding a great success on the HVACR control market. These small but essential components have earned an international prestige, the manufacturer’s abilities being congratulated and acclaimed by homeowners, industry leaders, commercial application owners, HVACR wholesalers, OEM’s, engineers and even by the manufacturer’s competitors.

The damper actuator product range is set under the trademarked name of OpenAir. OpenAir™ has been the manufacturer’s ambassador for quality, reliable service life and optimum added value, all of these coming at an extremely good price. The line of OpenAir™ damper actuators consists of two types of devices: Their rotary actuators (series GCA, GIB, GBB, GLB, GDB, GMA and GEB) and their linear actuators (series GBB, GEB, GLB and GDB).

Their rotary actuators have some distinctive features that apply to all models. Their design is superbly crafted to be both eye-pleasant and compact (as with all Landis Staefa and Siemens products). Their size and structure allows for installation in cramped environments. The reason they are called rotary actuators is obviously their ability to be rotated around. They can be rotated to up to 90 degrees and have a torque ranging that goes from 5 to 35 Nm. All models have an operating voltage of either AC 24 V or AC 230 V and the actuators deliver 2 position, 3 position or analog control signals.

The GCA series consists of rotary air damper actuators operating at 16 Nm and holding a spring return feature. They have a self-centering shaft adapter and a position indication characteristic. Other benefits of the GCA series include a manual override setting, adjustable mechanical limit stops, die-cast aluminum housing and an IP 54 degree of protection. The models from the GCA series have the following dimensions: 100 x 300 x 75 mm.

The GIB series are actuators operating at a 35 Nm torque rating and they come without a spring return feature. They are similar in degree of protection and size to the GCA models and they also hold a manual override button, which comes in extremely handy at times.

The GBB damper actuators operate at 25 Nm and hold a self-centering shaft adapter that can be used in shafts of 25,6 mm in diameter with a minimum shaft length of 20 mm. They can focus on a maximum air damper area of 3 m² and the running time for 90” is of 150 seconds. They come with a 0.9 meters connecting cable and offer a die-cast aluminum housing.

The smaller, more compact GDB models operate at only 5 Nm and come without a spring return feature. They are used in shafts of diameters of up to 16 mm, square 12 mm and a minimum shaft length of 30 mm. Their small size (68 x 137 x 59.5 mm dimensions) gives you the opportunity to install these damper actuators in the most unfriendly environments.

The GMA rotary air damper operates at a torque rating of 7 Nm and comes with a spring return. The models offer a position indication and adjustable mechanical limit stop and their compact size provides the following dimensions: 81 x 192 x 63 mm.

The last series from the rotary damper actuator category, the GEB, has a higher torque rating (15 Nm) at approximately the same dimensions as the GMA models: 81 x 192 x 60 millimeters. Their running time for 90” is 150 seconds and they come with a self centering shaft adapter.

The other big product section from their damper actuator product list, the OpenAir linear actuator models have some unique features. They operate at voltages between 24 V and AC 230 V and they deliver 2 position, 3 position or analog control signals. All actuator models are pre-cabled and their force ratings range from 125N to 440N. The strokeranging margin is of approximately 65 millimeters (between 60 and 70 millimeters). Their linear damper actuators include the following models: the GBB, the GEB, the GLB and the GDB damper actuator.

The GBB series are non spring-return linear actuator models, operating at a force of 550 N. They have a nominal stroke of 70 mm and a running time of 150 seconds. Other features include a manual override button and a die-cast aluminum housing, plus a connecting cable of 0.9 meters. They have quite a large size, the GBB actuators having the following dimensions: 100 x 298 (or 373 if their push rod is extended) x 675 millimeters.

The GEB, GLB and GDB series offer the exact same features and characteristics as the GBB series, but they operate with different force amounts and come in different sizes. For example, the GEB has a force rating of 400 N and its dimensions are as follows: 81 x 212 (272 with the push rod extended) x 60 mm. The GLB damper actuators work at a 250 N force and their dimensions are 68 x 152 (215 with the push rod extended) x 59 mm. Last but not least, the GDB series offers models that work at a lower force rating of 125 N and they have the same dimensions as the GLB series: 68 x 152 (215 with the push rod extended) x 59 mm.

The Landis Staefa line of actuators for dampers provide unparalleled control of air flow with an air duct system. Think of dampers as the valves that control air movement within any closed systems such as the ducts of a heating, ventilation and air conditioning or HVAC system. The actuator is a an electric motor, controlled by a thermostat or controller, that opens or closes the damper. Think of it as the remote control for the HVAC system. The actuators can also be used in industrial settings to control the flow air in some processes.

The actuators manufactured by Landis Staefa as part of its OpenAir product line are available in two basic configurations with a number of sizes within each configuration. The rotary line of actuators turn the control surface of the damper. For dampers that operate by a lever, Landis Staefa manufactures actuators that produce a linear movement.

Rotary actuators offer a compact size that allows them to fight in the tight confines of some HVAC systems. The devices are available in a number of powers with the higher power units necessary to operated dampers used in high air pressure configurations. The actuators can be operated at either 24 or 130 AC volts, depending on the controller used in the system.

The linear portion of the OpenAir actuator line has many of the same features. It also can operate on either of the standard voltages and is available in a number of sizes and strengths. The linear line offers another option with spring loaded or non-spring loaded actuators. Spring loaded actuators return the damper to the closed position when the current from the controller ends. Non-spring loaded actuators require another current from the controller to close the damper.

All OpenAir damper actuators are manufactured with a durable metal housing and on board override controls for use during repairs or in case of failure.

The OpenAir line of actuators from Landis Staefa work well with dampers from any of the reputable lines of manufacturers and can be operated by thermostats and controllers from most companies. The company brings a 65-year tradition of quality to the products offering some of the best quality HVAC components available.

Using the best quality components in a heating and cooling system reduces the possibility of failures that can lead to downtime and maintenance costs. These components also help reduce the overall cost of operation by requiring less maintenance while boosting the comfort level within the home or business.
