Technical Tips

How to read nozzle numbers:

Nozzles used on wands have a set of 4, 5, or 6 number, which give information about flow and spraying angle.  The first two or three numbers indicate the spray angle in degrees, listed normally as 80, or 95, or 110 are used with carpet cleaning, but other angles, such as 05 or 25, are also available.

The second group of numbers (the last 2-3 numbers), indicate the flow that will pass through each nozzle at 40 PSI.  Numbers such as 015, 02, and 03 are common numbers.

 

How to read nozzle sizes, angle of spray:

Size	Angle @ 40 PSI	Angle @ 200 PSI
110	110°	122°
95	95°	111°
80	80°	90°
65	65°	79°

The first 2 or 3 numbers in the Nozzle ID indicate the angle in degrees at 40 PSI.  Note that angle increases at higher pressures.

 

How to read nozzle sizes, flow:

The last 2 or 3 numbers in the Nozzle ID indicate the nozzle size in Gallons per Minute at 40 PSI. Note that flow increases at higher pressures.

Size	Flow @ 40 PSI	Flow @ 200 PSI	Flow @ 600 PSI
01	0.1 gpm	0.2 gpm	0.4 gpm
015	0.15 gpm	0.3 gpm	0.6 gpm
02	0.2 gpm	0.4 gpm	0.8 gpm
03	0.3 gpm	0.6 gpm	1.2 gpm
05	0.5 gpm	1.0 gpm	2.0 gpm

 

 Examples:

110015 = 110° 0.15gpm                        11003  = 110° 0.3gpm

9502      = 95°   0.2gpm                           8003    = 80°   0.3gpm

6506      = 65°   0.6gpm

 

The charts above are useful to verify that you are using the right angle nozzle on your wand.  Find the angle of nozzle that you are using, measure the distance to the vacuum opening.  Check to see if you have the width of coverage that you need.  Replace nozzle as needed to get the proper coverage and proper flow.  Typically, most 4 -jet wands should have 95015 or 110015 nozzles.  Note that 2 jet wands will have 9502 or 11002 nozzles.

Remember that the correct size nozzle will provide good coverage, keeping heat in the solution for better cleaning and faster solution removal for carpets to dry quickly.
