Problems solved by technology
[0015] However, the additional piping and shut-off valves cause additional pressure drop and create an additional risk of gas leaks, which has an impact on the energy efficiency of the machine
[0016] In addition, additional piping and shut-off valves create additional filter installation complexity, which means higher installation costs, larger filter installation sizes and Longer filter installation time

Embodiment Construction
[0052] figure 1 A filter device 1 according to the invention is shown for separating impurities from a gas.
[0053] The gas may be, for example, compressed air, but the invention is not limited thereto.
[0054] The aforementioned impurities may be oil, water and / or dust.
[0055] The filter device 1 comprises a filter housing 2 consisting of a cover 3 and a pot 4 which can be mounted on top of each other to form the filter housing 2 .
[0056] In the example shown, the can 4 is screwed into the lid 3 , wherein both the lid 3 and the can 4 are provided with mating threads 5 .
[0057] It is not excluded that the canister 4 is fixed in the lid 3 by means of a bayonet fitting or otherwise.
[0058] The cover 3 is provided with an inlet 6 for the gas to be purified and an outlet 7 for the purified gas. Typically, the filter unit 1 with the cover 3 is installed in the duct of a machine, such as a compressor unit. For this purpose, the cover 3 is provided with suitable flange...

The invention relates to a filter device and a method for switching on and / or switching off a filter device. The filter device is used to separate impurities from the gas to be purified, including a filter housing composed of a cover and a tank; the cover is provided with an inlet for the gas to be purified and an outlet for the purified gas; a filter element is installed in the tank, which consists of a top cover, The bottom cover and the filter element between the top cover and the bottom cover; the top cover is provided with an inlet pipe, and the inlet pipe inlet can be connected to the cover inlet, so that the gas to be purified enters the filter element through the inlet pipe; there is a space between the cover and the top cover, The space can be connected to the cover outlet; the filter device is also provided with a switch element with an inlet port and an outlet port, the switch element is rotatably mounted in the cover, the switch element can be rotated between a closed position and a twisted position, in the closed position The inlet port or outlet port is connected to the inlet or outlet of the lid respectively, in the twisted position this is not the case and the inlet of the inlet duct of the top cover can be connected to the inlet of the lid.
Description
technical field [0001] The invention relates to a filter device and a method for switching the filter device on and / or off. [0002] More specifically, filter devices are used to filter out impurities such as oil and dust from gases such as compressed air. Background technique [0003] Known filter devices comprise a filter housing in which a filter element can be placed. The filter housing consists of a lid and a canister that houses the filter element, the lid is usually screwed onto the canister or attached to the canister with a bayonet fitting. [0004] The cover is provided with an inlet for the gas to be purified and an outlet for the purified gas. [0005] The filter element itself includes a top cover, a bottom cover and a filter element between the top cover and the bottom cover, and the filter element is composed of filter materials. [0006] The top cover is provided with an inlet pipe, which can guide the gas to be purified to the inside of the filter element...
