P&J are experts in the installation of extraction systems.


Our fully trained, qualified, experienced engineers and fleet of fully stocked vehicles allows you to benefit from safe installation, completed on schedule with minimum disruption to your workplace.

The process of installation may introduce health and safety hazards such as work at height, manual handling, electrical hazards and potential exposure to asbestos. Prior to the installation date our installation co-ordinator will have ensured that a safe scheme of work has been agreed and you have approved the risk assessments and method statements (RAMS) for your site.


Why you should use P&J's installation services


  • P&J have specialised in the installation of LEV equipment since 1980.

  • P&J's directly employed installation engineers are highly skilled, experienced & qualified

  • You are assured of a high level of expertise, attention to detail and quality control.

  • Our installation engineers are uniformed, security DBS cleared and carry corporate photo ID.

  • Each installation is managed by P&J's installation co-ordinator to guarantee your total satisfaction.


You are legally required to check the competence of operatives working on your premises, especially with regard to:


  Health & safety training,

  Working at height,

Once all of the component checks have been completed your LEV system will be assembled and the duct work installed. When the mechanical installation is complete the system is ready for electrical installation. The commissioning test will be undertaken after the electrical installation has been completed. For every installation, P&J provide user training, a system manual and a log book for the operator to record the user checks. A comprehensive commissioning report is issued which sets the performance parameters that are referred to in the subsequent annual LEV tests (some processes need to be tested more frequently.)


For every P&J installation you will receive three documents:


        A user manual describing what the LEV is designed to control, and how it achieves control. It should also contain the following:

  • the LEV description, with diagrams

  • the LEV performance from commissioning

  • checks, maintenance and parts replacement schedules

  • description of the statutory 'through examination and test' and exposure targets

  • signs of wear and control failure to look out for

  • description of how operators should use the LEV so it works effectively and

  • a list of replaceable parts.


       A logbook that includes:

  • schedules for regular checks and maintenance

  • records of checks, maintenance, replacements and repairs

  • checks that the LEV is being used in the right way and 

  • the name of the person making the checks. 


      A commissioning report that includes:

  • a statement whether or not the four key statutory obligations under COSHH are achieved:

    • the system is effectively controlling the hazardous substance

    • the system is in good condition

    • the system is clean

    • the system is being used correctly

  • diagrams and a description of the LEV

  • photographs

  • details of the LEV performance specification and whether or not this is being achieved

  • pressures and air velocities at stated test points

  • calculations made

  • written descriptions of commissioning, the tests made and the outcome 

  • air sampling results 

  • filter efficiences 

  • concentration of the contaminant in the cleaned air if returned to the workplace

  • a description of how operators were using the LEV and how they should by using the LEV so that it works effectively

  • a prioritised action plan detailing any improvements or best practice recommendations.
