Specications
Cautions and maintenance
1. This device should be used with nebulizer only.
2. Place the device and nebulizer on a at, horizontal surface while in use.
3. The device must be in a vertical position while in use.
4. Turn the regulator slowly to avoid possible damage.
5. Do not completely unscrew regulator stem.
6. Do not attempt to disassemble the device.
7. Avoid excessive vibration, physical impact and dropping.
8. Do not store the device in direct sunlight, high temperature or humidity.
9. Keep the device away from static electricity.
10. For the rst use, open the rubber vent-plug on the back side of pressure gauge and
then close it in order to balance the pressure after the transportation.
Note: Do not open the rubber vent-plug when the device is in a vertical position to avoid
leakages of oil material from the pressure gauge.

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.
