Oil separator

A system comprising:

• a compressor that supplies compressed air;
• an air dryer that dries the compressed air supplied from the compressor and supplies dried compressed air, the air dryer comprising a supplying line that supplies the dried compressed air and an exhaust line that discharges purge air;
• and
• an oil separator connected to the exhaust line, the oil separator comprising:
• a housing including an inlet for introducing purge air from an air dryer and an outlet for discharging cleaned air, wherein
• the oil separator is configured to cause the purge air to flow into the housing form the inlet to separate oil from the purge air, thereby collecting liquid containing oil, and to discharge cleaned air from the outlet,
• the oil separator further comprises:
• a collected liquid storage portion that is located below the housing and stores the collected liquid;
• and
• a drain outlet located below the housing for draining the collected liquid.

A system comprising:

• a compressor that supplies compressed air;
• an air dryer that dries the compressed air supplied from the compressor and supplies dried compressed air, the air dryer comprising a supplying line that supplies the dried compressed air and an exhaust line that discharges purge air;
• and
• an oil separator connected to the exhaust line, the oil separator comprising:
• a housing including an inlet for introducing the purge air from the air dryer and an outlet for discharging cleaned air;
• an accommodation member, which is located in the housing and communicates with the the inlet in the vertical direction, the accommodation member comprising a wall portion configured to connect to the housing and defining a side face, wherein the accommodation member accommodates an impingement member and a through hole is formed at the side face of the accommodation member;
• a communication section that connects the inside of the housing and the outlet to each other;
• and
• a collected liquid storage portion located below the accommodation member, wherein
• the oil separator is configured to introduce the purge air into the housing through the inlet, and cause the purge air to strike the impingement member to separate oil from the introduced purge air, thereby collecting the oil,
• the inlet and the outlet are located in an upper section of the housing, and
• the accommodation member separates oil from the introduced purge air and discharges the separated oil downward.

A system comprising:

• a compressor that supplies compressed air;
• an air dryer that dries the compressed air supplied from the compressor and supplies dried compressed air, the air dryer comprising a supplying line that supplies the dried compressed air and an exhaust line that discharges purge air;
• and
• an oil separator connected to the exhaust line, the oil separator comprising:
• a lid including an inlet for introducing purge air from an air dryer and an outlet for discharging cleaned air;
• a plurality of expansion chambers arranged next to one another in a vertical direction;
• a housing attachable to the lid;
• and
• an attaching and detaching mechanism for allowing the lid to be attached to and detached from the housing, wherein
• the oil separator is configured to cause the purge air to flow into the housing and strike an impingement member to separate oil from the purge air, thereby collecting liquid containing oil, and the oil separator discharges cleaned air, and
• a through hole, which permits the purge air introduced through the inlet to flow vertically downward, is formed between the expansion chambers.
