Spring
Spring is a self-cleaning drum filtration system with a fixed metal filter cloth, suitable for removing magnetic and non-magnetic particles from neat and emulsified oils. It is available in 9 models with flow rates from 25 to 1000 l/min neat oil and 50 to 2,000 l/min emulsion. Drum filtration efficiency can be customised according to customer requirements.
Spring series self-cleaning filters are suitable for many types of machine tools such as: machining centres, deep drilling, transfers, grinding machines, lathes, machining with special high pressure tools and combined machines.
Losma guarantees that each purifier is individually tested through rigorous control procedures. A quality and functional test certificate is issued for each unit.
The Spring system uses a metal filter cloth which is cleaned by the Autoclean system. In this way, no consumable materials are used, significantly reducing maintenance and waste disposal costs.
This is an automatic cleaning system for the wire cloth used for filtering liquids. Inside the filter is a sensor that rotates the drum when the maximum filter cloth clogging level is reached. During the rotation, a countercurrent jet system washes the wire mesh, removing the residue while the dredging system scrapes the sludge from the bottom of the tank, transporting it to the outside.
It is used for the evacuation of filtered and decanted sludge; it can also be in a magnetic version for ferromagnetic residues.
The Spring and Spring Compact operating principle involves three phases:
- The filter cloth covering the drum is perfectly clean. The dirty liquid passes through it, depositing the polluting parts, and it finds the drain opening while passing inside it. Here, the liquid falls into the clean collection tank, from where it is then sent back to the machine tools. During this phase, the drum does not rotate and the dredging system is stationary. The pollutant material that settles on the cloth forms the actual filter layer, which can be up to 10-15mm thick.
- The filter cloth becomes dirty and the liquid level rises. The dirty liquid continues to deposit pollutants on the surface of the drum, which does not rotate and the dredging system is stationary. The degree of filtration improves due to the thickness of the sludge deposited on the cloth.
- When the cloth clogging cycle is complete and the liquid can no longer pass through, the best possible degree of filtration is achieved. The longer the filter runs in this condition, the better the average filtration will be. When the liquid in the clean tank reaches the minimum level, the Autoclean cycle starts automatically and the drum rotates. At the end of this phase, the cleaning cycle starts again from the beginning.

Magnetic rotating disc pre-filtration system for separating magnetic pollutant particles from coolant.
To facilitate the evacuation of ferro-magnetic swarf.
For supplying all utilities, controlling and managing all signals.
It is used to reduce the volume of sludge for disposal and to reduce the liquid it contains. However, the level of compaction that can be achieved depends on the type of sludge, the type of liquid and many other factors such as cycle times. Volume and moisture reduction is achieved by squeezing with static load. It has a volume reduction efficiency of 40% to 20% and liquid reduction efficiency of 30% to 10%.
For clean liquid delivery from 0.1 bar to 100 bar.
Eliminator of superficial oils allowing the quality of coolants to be maintained for a long time and eliminates odours generated in the presence of anaerobic bacterial flora.
To collect the clean liquid to be returned to the machine tool.
To collect dirty liquid for filter supply.
