Breathing air systems supply air of specific minimum purity to personnel for purposes of escape and protection when exposed to a toxic environment resulting from an accident or during normal work where conditions make breathing the ambient air dangerous. Breathing air systems must be installed with hardware that maintains a 4-1 safety factor on projected pressure. There are three basic types of breathing air systems: constant flow, demand flow and pressure demand.

Brewery plants are referred to beer making machine. It is used to produce beer. All styles of beer can be produced, which ranges from ales to lagers. Each brew operation is performed in a separate vessel. The machine contains parts such as, pressure gauges, sampling valves, level-gauge, thermo-wells and fermenter. Fermenters, serving tanks and bright beer tanks may have manway doors either on the top or on the side of the tank. Pressure gauges are attached to a diaphragm shell, which passes the pressure to the gauge's bi-metal sensor. The diaphragm is laser-welded to the fitting to avoid direct contact with the gauge. A 6″ clamped stainless steel thermo well is used to avoid direct contact of a thermometer or sensor with the beer. This brewery plant made up to 25.000 hl of beer per year.

Brick and salt cleaners eliminate white residues and harmful effect of salt. It is designed for use in carpets and floors. It alleviates white residues, rejuvenates brick and masonry and eliminates grayish dinge and weathered look. It is non-abrasive and non-caustic cleaner.

The brick cutter incorporates adjustable bars for measuring the length required, and provides the means to cut the brick simply by hitting the spring-loaded bolster with a club hammer. When constructing a building from bricks or blocks it is necessary to cut bricks to the required size, positioning at the end of a wall. These are used to reduce the risk of cutting a brick to an incorrect size or unevenly. These are requiring two blades to ensure an even cut which increases the cost of the device.
