Suitable for light weight doors like terrace doors that is often created of lightweight aluminum body with mesh screen overlaying nearly half of it. This door closer is usually made of aluminum tubing or cylinder with only the push rod exposed while the spring is hidden inside. The principle employed is very simple, a spring mechanism pulls the door with a small tension and whenever you open it further tension from the string is developed which force the doorway to close when released. The frequent problem with spring loaded door closer is that the push rod can be easily twisted if not installed properly or should you open the door excessively. Also the piston rod bearing or bushing in the front end which absorbed the linear load wears in the long run.

One more type of door closer is the air-driven door closer. They’re really identical to their spring loaded cousins with respect to load capacity and overall look. It also utilizes the same aluminum tube frame and has a piston rod. The primary difference is that it uses pressurized air instead of springs which is produced whenever you open the door compressing the air within then pulls and close the door whenever you release it. Also the inner design is slightly different.

In the spring loaded door closer there is no rubber seal at the piston or it is not air tight while in pneumatic doorway better, a rubber seal is installed to keep the air from getting out. With no rubber seal to keep the air pressure or when it is damaged will cause the device ineffective.

It is best to use in large weight doors and is often used in front doors or primary doors. The closing speed is adjustable using the turn of the screw. With the mounting template (to mark holes for drilling) and installation instruction bundled in the package making it quite simple to mount (drill required) and does not need a specialist to do them. Unlike pneumatic air, hydraulic fluid isn’t compressible, so, it is feasible to change the closing from the door at a really low speed and smoothly.

There are also other kinds of automatic door closer such as the motorized automatic door closer. Actually it is not only for closing but for opening too that is very convenient for hands free of charge, disabled and handicap access. This system uses a 24 VDC motor to work and controlled by a microprocessor which enables you to open and close the door both by hand and automatically. The encoder which is coupled to the DC motor detects the angle from the doorway at all times, which means the encoder can determine if the door is open and how much and responds consequently.
