Pneumatics is nothing but a branch of engineering that uses gas or pressurized air. In engineering, these pneumatic systems can be a cost-effective and preferred choice for designing commercial buildings. These control system uses compressed air as a medium to control HVAC systems. The compressed air in the system is carried via plastic or copper from a controller to a control device (which is usually a damper or valve actuator). You can manage or maintain the flow in your HVAC systems with Black hawk supply pneumatic controls. Pneumatic damper actuators that are dependable provide proportional control of dampers in independent operations or sequence operations. Pneumatic thermostats are used to control the pneumatic damper actuators and valves in cooling and heating applications. Sensing probes are used to find out the air pressure in your HVAC system.

pneumatic controls

At Black Hawk Supply, pneumatic controls are available in different sizes and in a variety of configurations to suit all your heating and cooling needs. Black Hawk Supply provides you a chance to choose from their large selection of pneumatic HVAC controls and accessories, including adapted bonnets, actuator mounting kits, thread adaptors, ring pack packing kits and more. The control method of pneumatic mainly depends on sensors and thermostats that retain the line pressure from the sensor to the actuator and to the control device.Each senor present responds and reacts to the changes in temperature, status pressure and humidity to provide feedback in a control loop to close or open the actuators to meet the required control set point. These actuators consist of springs and diaphragms to work in sequence with the control signal provided. This control system uses only the compressed air as the communication method. Each thermostat in a commercial or residential building with a pneumatic system has one or more air lines that are connected to it directly from the main source of compressed air and to some final device such as a valve.

Pneumatic actuators are the air-powered motors that control dampers and valves. They are the most durable, reliable, and economical actuators available. As an additional benefit, they require no high maintenance except for adjustment and inspection of mechanical linkages. It is simple and easy to detect actuators which fail in the desired position upon loss of electric power or pneumatic air pressure.

The pneumatic systems should be distributed throughout the building by using numerous pneumatic building blocks such as thermostats, pneumatic relays, and receiver controllers. Pneumatics systems can provide outstanding control performance, and they can maintain set points accurately.
