Improve the quality of the working environment

An increasing attention to environmental safety and protection in workplaces has been registered in the last decades from economical as well as political players: companies, users, control authorities and agencies who are strongly committed in respecting new regulations and operational guidelines.

All manufacturing companies are directly involved on these topics, especially those using machine tools, which employs coolants (neat oils or emulsions). Due to mechanical, thermic or pressure operations these liquids generate a mix of pollutants such as: mists, vapor, smoke and odors; with or without dusts and metallic swarf depending on worked material.

Air and coolant filtration systems are necessary to eliminate this pollutant mix from the workplace and can face different needs:


If pollutants disperse in the air and are inhaled by people working on the machine tools, they could lead to serious health risks. Eliminating oil mists and metallic micro-particles from the workshop helps to prevent respiratory and dermatologic disease and allergies, dangerous for all employees.

Oil particles deposit onto surrounding surfaces (floor, walls, etc.) and on machine tools, threatening their good operation; thus, air filtration can prevent those accidents caused by slippery surfaces and diminish risks of fire and short circuit caused by the deposit of oil in electrical controls or electronic devices.

losma safety 


Oil mists and coolant filtration assists to secure a cleaner workplace and reduce maintenance costs. Avoiding oil particles deposit on surfaces, increases not only the safety of workplaces but also limits cleaning costs and reduce maintenance interventions and breakdown events.

Installing a filtration system for air or coolant allows to reduce both cleaning and maintenance costs for workplaces and those connected to special waste disposal. Once cleaned from pollutant particles coolants can be re-used in the machining process, thus securing savings derived from a longer life. Finally, all Losma systems are designed to grant the better performances with low energy consumption, contributing to the corporate’s energy saving program.

Caring for the environment

Supplying high quality and eco-friendly products represent the core of our company mission since the beginning, and the commitment is underlined by ISO 9001 and ISO 14001.

“Working clean, Breathing healthy” summarizes the company philosophy and becomes real in the continuous research for filtration solutions more efficient and eco-compatible. Every Losma system, both oil mist and dust collectors or coolant filters, is tested through strict control procedures, to obtain a certificate for quality and function.

R&D department constantly research new solutions to improve existing products and to offer cutting edge solutions for filtration and depuration to the market. All Losma systems are designed to satisfy three main characteristics:

Eco-friendly products

high efficiency motors, restorable filters, power regulation inverter are just some of the solutions adopted in the range of Losma’s mist collectors and coolant filters, to meet European regulations requirements for company plants for environmental management.

Environmental protection

installing a filtration system for neat oils or emulsion allows to clean the liquid from pollutant particles and re-use it into the machine tool. This system reduces the quantity of industrial environmental special waste, extending coolants life. Air filtration for oil mists and smoke allows cleaner air to release it back into the workshop, permitting cost-savings for heating in winter and air conditioning in summer.

Better productivity

re-using a clean coolant in the machine tool allows to reduce the number of flawed pieces during production; because the pollutant particles, which increases the margin of errors, have been removed. Moreover, an efficient depuration system allows to reduce machine stops for maintenance.
