Equipment for Industrial Maintenance Technicians

The choice between a piston and a screw compressor depends on the duty cycle and the air consumption of the tools. The piston type suits intermittent use and short jobs, while the screw compressor is designed for more continuous operation in the plant. Compare the flow rate in litres per minute and the maximum pressure with those required by the tools you will use. Also consider the noise level and the space available in the workshop.

The dryer reduces the moisture in compressed air, which can condense in the pipework and damage tools and paintwork. It is useful when the air feeds precision instruments, spray painting systems or machinery sensitive to water. It must be sized according to the compressor's flow rate and the air quality required. In the system it is also advisable to include a condensate drain.

The FRL unit combines a filter, a pressure regulator and a lubricator, and is installed before the pneumatic tools. The filter retains impurities and condensate, the regulator keeps the pressure constant and the lubricator doses the oil to protect the internal parts. The lubricator is not always needed, because some tools require clean air without oil. Always check the tool manufacturer's instructions.

Metal drill bits are chosen according to the material to be drilled, its hardness and the hole diameter. For steel, a quality bit with a moderate rotation speed and a lubricant during the work is best. For plastic you need bits with dedicated geometries, because those designed for metal can overheat the material. The diameter should be chosen according to the wall plug or screw you will insert in the hole.

The hand-operated winch lifts or drags loads by means of a rope wound on a drum. Respect the capacity shown on the plate, which in this collection ranges from 540 to 900 kg depending on the model. Do not work under a suspended load and check that the anchor point is solid. Check the rope before each use and avoid letting it work when kinked or worn.

Industrial maintenance requires safety glasses, gloves and footwear suited to the risks present, as well as hearing protection when working near compressors and noisy machinery. The choice depends on the risk assessment of the area where the work takes place. Italian Legislative Decree 81/2008 on workplace safety governs PPE (personal protective equipment): the employer must provide suitable equipment and the worker must use it.

Fully threaded hexagon head screws in A2 stainless steel are used where corrosion resistance is needed, for example in damp environments or in contact with water. The A2 code indicates a class of stainless steel, while DIN 933 refers to the shape of the screw. Check the length according to the thickness to be joined and use nuts of the same material. Avoid combining different steels, so as not to encourage galvanic corrosion.
