Rossmax Neb Tester is a portable and easy-to-use device that allows the user to quickly
check the performance of the pump of a compressor nebulizer. Power source is not
required for Neb Tester during operation and the test result is easy to read and interpret.
Neb Tester consists of an oil pressure gauge, ow meter, air tube and stainless steel stand.
This device is used to simulate the working conditions of the pump when the nebulizer is
in operation with a medication cup, and you are able to check:
1. Maximum (free) air ow
2. Operational air ow at a particular pressure
3. Maximum air pressure

1. Check maximum (free) air ow
Step 1: Turn the regulator of ow meter anticlockwise around 2~3 circles.
Step 2: Insert the other end of air tube into the air outlet of the nebulizer.
Step 3: Power on the nebulizer.
Step 4: Keep the nebulizer running for 30 seconds to warm up.
Step 5: Adjust air ow and set the level of the pressure at 0 PSI by turning the
regulator of ow meter.
Step 6: Check the air ow rate.
Step 7: Turn off the nebulizer.
Step 8: Disconnect the air tube from the nebulizer.
2. Check operational air ow at a particular pressure
Step 1: Turn the regulator of ow meter anticlockwise around 2~3 circles.
Step 2: Insert the other end of air tube into the air outlet of the nebulizer.
Step 3: Power on the nebulizer.
Step 4: Keep the nebulizer running for 30 seconds to warm up.
Step 5: Set the pressure to a desired level by adjusting the regulator of the ow
meter.
Step 6: Check the air ow rate.
Pressure (PSI) Flow rate (L/min)
NA100 / NB500 (N1) 15.0 ≥ 3.5
NE100 / NF100/ NJ100 (N4) 15.0 ≥ 3.5
NK1000/ NB80 / NF80 (N1) 8.0 ≥ 3.0
NB60 / NI60/ NH60 / NF60 (N1) 8.0 ≥ 2.0
NL100 (N2) 10.5 ≥ 3.5
Step 7: Turn off the nebulizer.
Step 8: Disconnect the air tube from the nebulizer.
3. Check maximum air pressure
Step 1: Turn the regulator of ow meter anticlockwise around 2~3 circles.
Step 2: Insert the other end of air tube into the air outlet of the nebulizer.
Step 3: Power on the nebulizer.
Step 4: Keep the nebulizer running for 30 seconds to warm up.
Step 5: Set the air ow rate at 0 L/min by turning the regulator of ow meter
clockwise completely.
Step 6: Check the values on the pressure gauge.
Step 7: Turn off the nebulizer.
Step 8: Disconnect the air tube from the nebulizer.
