The Pump is a mechanical device using suction or pressure to raise or move liquids, compress gases, or force air into inflatable objects such as tires.


The Silencer is a device fixed to the exhaust of a motor vehicle to reduce engine noise.


The Condenser is an apparatus or container for condensing vapor into liquid. It is also known as heat transfer.


The Drier is a kind of substance or device to accelerate the drying or extract moisture.


The Muffler is a device used to reduce the noise of an engine or deaden the instrument's sound.


The Filter is a porous device for removing impurities or solid particles from a liquid or gas that passes through it.


The Nozzle is a cylindrical or round spout at the end of a pipe, hose, or tube used to control the direction, or the velocity of a gas or liquid flow.


The Pipeline is a long pipe, typically underground, for transporting oil, gas, etc.


The Chiller is a machine for removing heat from a liquid through a circle of vapor compression, absorption, and refrigeration.


HVAC Ductwork Symbols

The following HVAC ductwork symbols show the different ductworks and junctions: straight duct, miter bend, miter bend, 3-way junction, Y junction, and transition.

HVAC Ductwork Symbols

The Bend is a curve part in a road, river, path, or racing circuit.


The Y junction generally has 2 arms of equal size.

Y junction

The Transition is the process or a period of changing from one state or condition to another.


The VAV box is short for Variable Air Volume box, which is a type of HVAC system.


HVAC Controls Symbols

The following HVAC controls symbols include commonly used shapes that represent for measuring temperature, flow, velocity, voltage, current, light, timer, power, and more.

HVAC Controls Symbols

The Temperature shape shows a kind of device to measure temperature.


The Humidity shape shows a kind of device to measure humidity.


The Timer shape shows a device to count time.


The Air quality is a device to detecting air qulity.

HVAC Control Equipment Symbols

The following HVAC control equipment symbols include duct, sections, pipe, VAV box, heater, damper, boiler and more.

HVAC Controls Equipment Symbols

The Duct is a tube or passageway in a building or machine for air, liquid, cables, etc.


The Damper is a kind of device that has a subduing or inhibiting effect.


The VSD is a hole in the wall separating the two lower chambers of the heart.
