The VLF R Series from Envair guarantees superior product protection by offering a positive pressure particle-free working area achieved by initially pulling air through a G4 pre-filter (EN779:2012) and then pushing air through a High Efficiency Particulate Air (HEPA) filter type H-14 (BS: EN: 1822). This provides vertical laminar downflow air into the working area at a homogenous air speed across the filter face in a range of 0.36 m/s to 0.54 m/s.

The VLF R Series is designed for NHS hospital pharmacies for CIVAS (Central Intravenous Additive Service), TPN compounding and bagging, preparation of IV solutions and eye-drops, ampoule filling, etc.

It has been adapted and customised for integration of paperless medication workflow solutions such as BD CATO™, and automated compounders such as the Baxter ExactaMix® 2400.

The VLF R Series design is ideal when freedom of movement into and in the working area is paramount and when sited in a Grade B cleanroom. Otherwise you should consider our range of positive pressure isolators.

DESIGNED WITH CLEANROOMS IN MIND

The VLF R Series has been designed with the application in mind. All materials are specified to be non-shedding and resistant to common cleaning chemicals, with low noise and low energy consumption as standard with EC/DC fans and LED lighting (providing <750 lux in the work zone). This provides the most comfort and safety possible.

The VLF R Series is typically built to a clients URS, often including polished 316L stainless steel internally and externally, vari-height electrically operated height adjustable support frame, CCTV camera, sealed touchscreen monitor in rear wall of main chamber, power and data connection.

CONTROL AT YOUR FINGERTIPS

The VLF R Series is fitted with a Siemens KTP700 HMI colour display as standard. This is a PLC control system with touch control membrane and password protection for different levels of access control. It provides:

• Display of unidirectional flow velocity
• Display of HEPA filter differential pressure
• Power on/off indicator
• Fan on/off push button
• Lights on/off push button
• Latched audible and visual alarm for high filter pressure differential, high/low airflow and power failure
• Alarm mute function with user definable re-activation period (up to 30 minutes)
• Alarm log of last 10 alarm events

Key Features

  • Designed and built in the UK, with nationwide UK service support
  • Airflow velocity at 0.45m/s maintaining a perfect Grade A work area suited for ‘open’ processing tasks and aseptic manipulation of components
  • All dimensions can be customised to suit application and any large devices required in the work area
  • Controlled and monitored using a Siemens Programmable Logic Controller (PLC) with critical parameters and alarms displayed on a 7” Siemens colour touchscreen HMI mounted on the front of the cabinet
  • Transparent side screens and LED lighting to allow maximum viability and light to the work area
  • Choice of materials and finish to suit budget and application
  • Extensive list of options and customisations including table frame (manual and electric), Isokinetic head for particle monitoring, HD CCTV camera, touchscreen monitor, sockets and service taps
