Frequently Asked Questions - 9070 Hazet

What is the Hazet 9070 Maintenance Unit used for?

The Hazet 9070 series is designed to filter compressed air to remove dirt and rust, reduce inlet pressure to suit tools, and (for models with lubricator) lubricate the air to prevent corrosion.

What are the differences between models 9070-2/3/4 and 9070-5/6/7?

Models 9070-2, -3, and -4 include a lubricator in addition to the filter-pressure reducer, while models 9070-5, -6, and -7 are filter-pressure reducers only (no lubricator).

What connecting threads are available for the 9070?

The connecting thread sizes are 1/2" (models 9070-2 and 9070-5), 3/8" (9070-3 and 9070-6), and 1/4" (9070-4 and 9070-7).

What is the maximum working pressure for the 9070?

For models with 1/2" or 3/8" threads, the maximum working pressure is 12 bar; for 1/4" models it is 10 bar. The maximum inlet pressure should never exceed these values.

How do I adjust the output pressure?

Lift the pressure regulator knob upward, then turn it clockwise to increase pressure or counterclockwise to decrease. Once set, push the knob down to lock it in place. A final clockwise turn builds the desired pressure.

How do I drain condensate from the filter cup?

The condensate drain valve has three positions: central free position for semi-automatic drain (drains only when pressure is absent), push up for manual drain under pressure, and turn counterclockwise to close the valve manually.

What type of oil should I use in the lubricator?

Use suitable oils such as HAZET pneumatic special oil 9400-100 or ISO/UNI FD oils. For models 9070-3, -4, -6, and -7, GAV Sprinter ADPV 22L oil is also recommended. Avoid using other oils that may damage the product.

Can I install the unit in any orientation?

You must observe the airflow direction marked by arrows on the unit. Avoid installing in places subject to shock, vibration, high heat (above 60°C), or strong concentrations of alcohol or solvents.

How should I clean the cups?

Clean the cups with soap and water only. Do not use detergent oils, brake circuit oils, or solvents, as these can damage the cups.

Where can I find spare parts for the 9070?

For safety, only use manufacturer's original spare parts. Using non-approved parts voids warranty and liability. Contact Hazet or authorized dealers for genuine parts.

9. Before starting the operation

Prior to installation, please observe the air flow direction marked by arrows

• The filter-pressure reducer is equipped with a front and a rear outlet for the manometer. Close the outlet not being used with the threaded plug ⑧
• Before pressurizing the system, fill the lubricator with oil either directly by unscrewing the oil-cup ⑦ or through the oil filler plug ⑥ positioned on top of the lubricator body.

Always use suitable oils, such as HAZET pneumatic special oil 9400-100 or ISO and UNI FD oils.

10. Application

• Air pressure adjusting:

By operating the pressure regulator ② on top of the filter-pressure reducer

1. Raise the pressure regulator knob ② upwards in order to permit rotation
2. Increase pressure: turn the knob clockwise decrease pressure: turn the knob counterclockwise
3. Once the desired pressure has been obtained, push the knob downwards in order to lock it in place.
4. With a final clockwise rotation the desired pressure is built-up.

- Condensate drain

There is a condensate drain valve ④ in the lower part of the filter cup.

• Position ① – semi-automatic condensate drain: The valve knob is in central free position – valve closes if system is under pressure, condensate is drained only during the absence of pressure
• Position ② – manual condensate drain: Push the valve knob up to drain condensate manually even under pressure.
• Position ③ – manual valve closing: Turn the valve knob counterclockwise to close valve manually. Please take care to drain the condensate regularly

- Oil flow regulation

Use the oil flow regulator ⑤ on top of the lubricator in order to dose the oil quantity to be sprayed:

- turn the regulator knob clockwise to decrease the oil quantity

- turn the regulator knob counterclockwise to increase the oil quantity.

CAUTION:

The maximum inlet pressure must not exceed the values listed in the technical data.

• Do not expose the tool set to heat sources higher than 60°C.
• Avoid installing the maintenance unit and the filter-pressure reducer in places subject to shock, vibration, or other types of stress.
• Avoid installing the maintenance unit and the filter-pressure reducer in places with strong concentrations of alcohol or solvents.
• Take care not to unscrew the cups or other parts of the maintenance unit or the filter-pressure reducer without first depressurizing the system.
• Keep tool set out of reach of children.
• Incorrect use may damage the product. It is therefore essential to scrupulously observe the contents of this application note.

11. Storage

The tool set has to be stored according the following conditions:

• Do not store the tool set outdoors.
• Keep tool in a dry and dust-free place.
• Do not expose the tool to liquids and aggressive substances.
  • Storage temperature: -10 up to +55 °C.
  • Relative air humidity: max. 65 %.

12. Maintenance and Cleaning

• Use only soap and water to clean the cups. Do not use detergent oils, brake circuit oils, or solvents.
• Regularly drain the condensate that forms in the filter cup.

CAUTION: you are advised to use models 9070-3, 9070-4, 9070-6 and 9070-7 with GAV Sprinter ADPV 22L oil.

The use of other oils can permanently damage the product if they do not comply with the required characteristics for lubricators.
