Client Overview
Our client is an engineering company based in Leicester, specialising in metalworking processes. Their facility operates multiple CNC machines, including two Hurco CNCs, seven Haas CNCs, an open lathe, a XYZ Machine 6, and a XYZ Proturn SCX 555. With so many machines in operation, controlling oil mist is critical to protect workers’ health and ensure compliance.
The Challenge
The company required an effective solution to capture and control oil mist generated during machining operations. Prolonged exposure to oil mist can have serious health implications, including bronchitis, lipoid pneumonia, lung fibrosis, and even lung cancer. The variety of machinery in use added complexity, as both enclosed CNC machines and open machines needed tailored extraction methods.
Our Solution
Impact Technical Services designed and installed a bespoke LEV system, tailored to the client’s mixed machine setup:
-
Central Extraction Fan – An RV-50-C2 fan was installed at ground level to provide the required airflow. The fan was fitted with a silenced discharge duct and weather bend to ensure safe, quiet extraction of contaminated air to the atmosphere.
-
CNC Machine Connections – Each CNC machine was fitted with a bespoke connection spigot, allowing safe and easy connection to the ducted system.
-
Open Lathe Solution – For the open lathe, a versatile RFF extraction arm was installed, giving operators flexibility in positioning the capture point.
-
Compliance – All ducting was designed and installed in line with HSE guidance HSG258.
The Result
Following installation, the system was fully commissioned, including fan vibration and noise testing, along with duct flow measurements. Once LEV testing was complete, the company received a comprehensive commissioning report to use as a benchmark for future thorough examinations.
The new system effectively controls oil mist across all machines, improving air quality, protecting operator health, and ensuring ongoing compliance.
