A pneumatic system installed on a vehicle and method of using the system to preheat compressor oil and/or components of the system to promote operation in cold weather conditions. The pneumatic system includes a compressor that generates compressed air in which oil is entrained, a separation tank that separates the oil from the air prior to the oil being returned to the compressor, and a heating element located within the separation tank and contacting the oil within the separation tank. Engine coolant of an engine cooling system of the vehicle flows through the heating element and the heating element transferring heat from the engine coolant to the oil within the separation tank to increase the temperature of the oil.

A vacuum pumping system which comprises a plurality of vacuum pumping arrangements for evacuating a flammable gas stream and exhausting the gas stream through an exhaust outlet. A housing houses the vacuum pumping arrangements and forms an air flow duct for an air flow for mixing with the exhaust gas stream output from the exhaust outlet in a mixing region in the housing. An airflow generator generates an air flow through the air flow duct to cause mixing of air with the flammable gas stream to a percentage of the flammable gas in the air flow lower than the lower flammability limit of the flammable gas. An airflow sensor senses the flow of air for determining if the air flow is sufficient to dilute the flammable gas to lower than said percentage.

Proposed is a through type drain pump for a fluid draining apparatus of a fluid pipe. The drain pump includes: a housing formed in a hollow cylindrical shape, the housing being configured such that a fluid inlet port and a fluid outlet port are in communication with each other via a fluid movement path; a rotary shaft having a driving motor, the rotary shaft being rotatably coupled to an output shaft of the driving motor via a coupler; an impeller formed at a lower end of the rotary shaft and configured to be rotated so that the fluid is moved to the fluid outlet port through the fluid movement path; and a mounter mounted at a lower outer side surface of the housing and configured to mount the drain pump on any pipe such that the drain pump is capable of being lifted and inserted into the pipe.
