Automatic Vacuum Switch [AVS] (Option) 

The AVS is used to control the vacuum flow in the gas scavenger breathing circuit and assure 
that the scavenging system is activated as soon as N

 is turned ON.  Adjust the vacuum 

flow using the control knob.  Vacuum flow is most effective when the ball float is set within the 
green bar area.   Installation of AVS to Flowmeter:  Screw AVS 5000 knurled seal nut down tight 
onto flowmeter making sure the rubber washer is inside the seal nut.  When tight, the AVS should 
not rotate.  Then, screw the bag tee seal nut onto the AVS.  Bag tee should not rotate.  
Connecting AVS to Vacuum Hoses:  Attach one end of the vacuum hose to the vacuum hose “Y” 
connector and the other end to the MASK port of the AVS. Attach a second vacuum hose to the 
VAC port of the AVS and the other end to the vacuum source.  Refer to FM-809 for User 
Instructions, Assembly, Installation and Cleaning. 
 
Porter recommends that effective scavenging can be achieved with the ball float in the green bar 
area of the acrylic sight glass, however NIOSH publications conclude that higher vacuum flows of 
up to 45 L/min are most effective.  To meet the NIOSH recommendation of 45 L/min adjust the 
ball above the green bar area. 

 
C A U T I O N :  

D O NOT PROCESS ANY LIQUIDS OR DEBRIS THROUGH THE AVS.  This 

contamination can cause damage and affect the function of the unit.  The AVS is designed to 
regulate the vacuum flow level for scavenging of Nitrous Oxide / Oxygen gas only. 

 
C A U T I O N :  

The vacuum system should be equipped with a back flow shutoff device to prevent 

carryover of fluids into equipment attached to the piping systems.  It is recommended that a 
separate vacuum trap be used between the piping system and the vacuum station inlet or any 
equipment that is attached to the system. 

 
 

In-line Vacuum Control Kit  (Option) 

The kit includes a vacuum control block with sight glass, vacuum tube holder, adapter “T” and 
straight fitting. The vacuum control block can be inserted directly into the High Volume Evacuation 
(HVE) line or may be placed “in-line” by cutting the vacuum hose and attaching the cut ends of 
the tubing to both ends of the vacuum control block.  Adjust the vacuum flow using the control 
knob.  Vacuum flow is most effective when the ball float is set within the green bar area. Refer to 
FM-809 for User Instructions, Assembly, Installation and Cleaning.
