The porter brown Vacuum Control block is a multi-application item. It can be used in three different ways:

· Connection to an AGS Adapter fit to an Anaesthetic Gas Scavenging System Terminal

· Connection to a High Volume Port on Dental Chair Suction

· Connection to a MiniScav

The first two items have a high suction and in these cases, the VCB is required to reduce the draw on the attached breathing system to the recommended working level of around 45 L/min. This is to prevent fresh gases being 'sucked' out of the system when the patient exhales and the inner liner flapper valve opens.

The Miniscav is different. These units, which are essentially a cased pump, are factory set at a draw level of 46 L/min - and in this case, the VCB is therefore only used as solid connection between the breathing system and Miniscav inlet. The black bobbin will not lift or adjust, but merely 'quiver' in the base of the channel. This, taken into conjunction with the quiet 'hiss' that can be heard at the nasal mask is the indication that everything is operating correctly.

This does mean that regular, documented maintenance on the MiniScav is vital, to ensure it is operating at the correct draw. The current service protocol for a MiniScav unit is:

Year 1 - service check on customer site.

Year 2 - service exchange of unit. This consists of a workshop serviced unit brought along by the engineer attending and 'swopped' for the existing 2 year old unit. The maintenance programme allows for repairs, service and upgrades that would not be able to be accomplished in the field.

It is important to understand that a VCB will operate differently when connected to a MiniScav. If you have any further queries with regard to operation please email: This email address is being protected from spambots. You need JavaScript enabled to view it.

Attending the BDIA Dental Showcase this year?  Why not plan in a visit to the R A Medical Services Ltd E135 where you will be able to view our comprehensive equipment range, talk to our friendly staff or attend a 20 minutes vCPD lecture on a variety of topics including:    

IACSD: The latest guidelines - up to the minute news by Richard Charon

Scavenging Overview: Stay Safe & Comply by Janet Pickles

IS as a Practice Builder - The Benefits: 8000 cases on...  by Richard Charon

IS Equipment Overview - The options and how to get started - by Janet Pickles

These will run throughout the three Show Days at regular intervals from Stand E135 - all welcome.  Times available from the Show Guide.

It has recently become apparent that the use of cleaning cloths with excess moisture are causing damage to R A machines - Analogue MDM's in particular.  The liquid is seeping into the interior of the machines and flowtubes.  This has various detrimental and damaging effects to the internal seals, valves and flowmeter tubes which will require workshop repair.  Great care should be taken to only use MOIST cloths with no excessive liquid - i.e. squeeze out any excess liquid from the cleaning cloth prior to applying the the machine.   The R A Head should then be gerntly polished with a clean, dry cloth.

If obvious liquid is observed inside the front perspex cover or flow tubes then this unit should be taken out of service immediately and the service provider contacted.  This is termed as accidental damage/customer mis-use and would not be covered under the equipment service warranty.  A return to workshop is indicated as the whole unit has to be stripped down and dried out - replacing all damaged components - before it can be returned to service.

BDIA code of practice





On the 21st September 2013, Janet & Chris Pickles attended the SAAD Symposium at the Royal Society of Medicine, London with a small display stand.


Dental Showcase in October 2013 saw R A Medical presenting the largest ever Show Stand - 60 square metres incorporating a lecture theatre.


For the first time in 10 years, R A Medical Services will be once again exhibiting at the BDA Conference and Exhibition being held at the Manchester Central Convention Complex between the 10th and 12th April 2014. Our stand A6, whilst somewhat smaller than usual, will still carry a comprehensive display of equipment and our friendly, knowledgeable staff will be on hand to answer any questions delegates may have. We will also be serving drinks and canapés from the stand at the Thursday evening Exhibition Hall drinks reception between 6-7pm - why not drop by for a drink, bite to eat and a chat?

This year sees the anniversary of the Company founding in February 1994. Started by Chris and Janet Pickles and using extensive experience gained from well over 30 years in the field of anaesthetic equipment it has grown to include their four sons in additional to a highly skilled team of office and engineering staff. Truly a family business with traditional values and attention to detail as the keywords.
