COMPACT VARIABLE-SPEED WATER PRESSURE
DAB E.SYBOX MINI3 Variable Speed Pressure System Pump
The DAB E.SYBOX MINI3 is a compact integrated variable-speed pressure system designed for domestic clean-water pressurisation, rainwater reuse, household water supply, gardening and irrigation.
It combines a self-priming three-stage pump, variable-frequency drive, pressure and flow sensors, integrated non-return valve, electronic protections, adjustable display and a 1-litre expansion vessel inside one compact enclosure.
The inverter automatically adjusts pump speed as water demand changes, allowing the MINI3 to maintain a selected pressure more consistently than a basic fixed-speed pump and separate pressure-controller arrangement.
Installed Today can offer the DAB E.SYBOX MINI3 as supply only across supported Australian locations or through eligible supplied-and-installed pathways in Brisbane and Gold Coast service areas, subject to the water source, suction conditions, pipework, electrical supply and required hydraulic performance.
DAB E.SYBOX MINI3 at a glance: up to 80L/min maximum curve flow, up to 55m maximum head, adjustable constant-pressure setpoint from approximately 1 to 5.5 bar, 7.5 bar maximum working pressure, 0.85kW maximum input, approximately 4.8A rated current, 1L integrated vessel, self-priming capability to approximately 8m under suitable conditions and approximately 45dB(A) sound pressure at 1m.
CURRENT PRODUCT
What Is the DAB E.SYBOX MINI3?
The E.SYBOX MINI3 is DAB's compact electronic pressure-booster system for residential water supply.
Its defining difference from a conventional pump is the level of equipment integrated into one package.
- Self-priming multistage pump
- Variable-speed inverter
- Pressure sensor
- Flow sensor
- Integrated non-return valve
- 1-litre expansion vessel
- Adjustable digital display
- Dry-running protection
- Overcurrent protection
- Overheating protection
- Anti-cycling protection
This reduces the need for the separate basic pressure-controller and pressure-tank arrangement commonly found on traditional domestic pump systems.
CONSTANT PRESSURE
How Does Variable-Speed Pressure Control Work?
Once the required pressure setpoint is configured, the E.SYBOX MINI3 monitors system pressure and water flow.
When demand is low, the inverter can operate the motor at a lower speed. As additional outlets open and flow demand increases, pump speed rises to help maintain the selected pressure.
Lower Demand
The motor does not need to operate at full speed whenever a small amount of water is required.
Changing Demand
The inverter changes motor speed as taps, showers or irrigation outlets open and close.
Consistent Pressure
The system attempts to hold the selected setpoint while the required flow remains within the pump's hydraulic capability.
Variable speed does not create unlimited flow. The pump can only maintain the selected pressure while the required duty remains within its performance curve.

ELECTRICAL SUPPLY
How Much Power Does the MINI3 Use?
DAB lists a maximum electrical input of approximately 0.85kW and rated current of approximately 4.8A on a 220–240V single-phase supply.
Current manufacturer material describes the system as supplied with its electrical lead and plug.
The property still needs a suitable electrical supply in the correct installation position.
Any new power point, circuit alteration or fixed electrical work required for a new pump location is additional installation work.
SELF-PRIMING
Can the MINI3 Draw Water From a Rainwater Tank?
Yes. DAB lists the E.SYBOX MINI3 as self-priming to approximately 8 metres under suitable manufacturer test and installation conditions.
This can make it suitable for selected above-ground tanks and other clean-water storage sources where the pump is installed outside the tank.
Actual suction performance depends on:
- Vertical suction lift
- Horizontal suction length
- Pipe diameter
- Air tightness of the suction line
- Number of bends and restrictions
- Foot or check-valve arrangement
- Water level changes within the tank
- Correct initial priming
The 8m figure is a maximum self-priming capability, not a recommended design target for every installation. Long or restrictive suction pipework can substantially reduce available flow and pressure.
CLEAN WATER
What Type of Water Can the E.SYBOX MINI3 Pump?
DAB specifies clean water that is free of solids or abrasive substances and is non-viscous, non-aggressive, non-crystallising and chemically suitable for the pump.
The MINI3 is therefore appropriate for compatible clean-water applications including domestic pressure boosting, clean rainwater reuse, gardening and irrigation.
The E.SYBOX MINI3 is not a dirty-water pump. Rainwater tanks containing heavy sediment, grit, sludge or debris may require tank maintenance and suitable filtration before a new pressure pump is installed.
POTABLE WATER
Can the MINI3 Be Used for Household Water Supply?
Yes. DAB identifies the E.SYBOX MINI3 as suitable for potable-water applications and lists ACS certification for the product family.
This means the pump materials and design are intended for compatible drinking-water systems.
It does not mean the pump filters, disinfects or otherwise treats the source water.
Where rainwater is intended for potable use, source quality, tank hygiene, treatment, filtration and the wider plumbing system remain separate requirements.
COMPACT DESIGN
How Big Is the E.SYBOX MINI3?
DAB's technical documentation lists dimensions of approximately 439mm x 263mm x 236mm.
The compact enclosure allows the pump to fit into installation spaces that would be difficult for a conventional pump, external pressure tank and separate controller.
DAB specifically promotes the MINI3 for compact installations and notes that appropriate installations can include locations such as beneath a kitchen sink.
Compact does not mean zero-clearance. The pump still needs suitable plumbing access, ventilation, electrical access and enough room for future service or removal.
INSTALLATION ORIENTATION
Can the MINI3 Be Installed Vertically or Horizontally?
Yes. DAB allows the E.SYBOX MINI3 to be installed in either a vertical or horizontal fixed position.
The control display can be oriented for easier reading in the chosen installation configuration.
A wall-mounted installation is also possible using the appropriate DAB mounting accessory and suitable structural support.
- Vertical installation
- Horizontal installation
- Wall installation using appropriate DAB mounting hardware
- Multiple hydraulic connection configurations
OUTDOOR INSTALLATION
Can the E.SYBOX MINI3 Be Installed Outside?
The standard MINI3 enclosure is rated IPX4, but that should not be interpreted as approval to leave the pump exposed to unrestricted weather.
DAB provides its E.SYCOVER accessory for suitable outdoor E.SYBOX and MINI3 installations.
An external location should provide the manufacturer-required protection together with appropriate drainage, electrical safety, pipework support and future service access.
QUIET OPERATION
How Loud Is the DAB E.SYBOX MINI3?
Current DAB manufacturer information lists approximately 45dB(A) at one metre in free field.
The water-cooled motor avoids a separate motor-cooling fan and the integrated enclosure helps manage operating sound.
Actual noise at a property can still increase through pipe vibration, rigid mounting, cupboards, walls and resonant building surfaces.
Good pipe support and installation positioning remain important where the pump is installed close to occupied rooms.
INTEGRATED PRESSURE VESSEL
Does the MINI3 Need a Separate Pressure Tank?
The E.SYBOX MINI3 already contains a 1-litre expansion vessel.
It also incorporates the electronic controller, pressure sensor, flow sensor and check valve needed for standard operation.
This is why DAB describes the product as an all-in-one or fully integrated pressure system.
Integrated does not mean installation requires no fittings. Isolation valves, unions, suitable pipework, filters or other hydraulic components can still be required for the actual property.
PUMP SIZING
How Many Taps Can the MINI3 Supply?
Older DAB marketing material has referred to applications with up to approximately eight open taps, but a simple tap count is not the most reliable way to size the current pump.
DAB's Australian pump-selection guidance positions the MINI3 primarily for a small house or unit and recommends assessing the actual application.
Correct selection should consider:
- Required simultaneous flow
- Desired pressure at the fixtures
- Number of bathrooms
- Building elevation
- Pipe diameter
- Pipe length
- Suction lift
- Filters and valves
- Garden or irrigation demand
Do not purchase solely from an “eight taps” headline. At 40L/min DAB lists approximately 39m of head, while at 80L/min only about 4m remains.
DOMESTIC APPLICATIONS
What Type of Property Does DAB Position the MINI3 For?
DAB describes the MINI3 as a pressure system for a single dwelling and compact residential applications.
Previous Australian manufacturer guidance has referenced apartments up to approximately three floors, two-bathroom applications and small garden areas, while the newer Australian selection guide more conservatively positions the MINI3 for small houses and units.
The hydraulic performance curve should therefore be used instead of treating those marketing examples as fixed capacity limits.
RAINWATER APPLICATIONS
Can the MINI3 Be Used With a Rainwater Tank?
Yes. Rainwater reuse is one of DAB's manufacturer-listed applications for the E.SYBOX MINI3.
The pump can draw clean tank water and provide pressurised supply to suitable connected outlets when the suction arrangement falls within the manufacturer's requirements.
The MINI3 alone does not provide automatic rainwater-to-mains changeover. If a property needs automatic mains backup when the tank is empty, that function requires an appropriate separate rainwater-management arrangement.
GARDEN & IRRIGATION
Can the MINI3 Run Garden Irrigation?
Yes. DAB lists gardening and irrigation among the intended applications.
The Australian manufacturer's pump-selection guide uses an example of up to approximately eight small static sprinklers at 6L/min each and 2.4 bar as an indicative MINI3 selection.
This is an example rather than a universal irrigation capacity. Sprinkler flow and operating pressure vary significantly between irrigation products.
BUILT-IN PROTECTION
What Protection Does the E.SYBOX MINI3 Include?
DAB's electronic control platform includes protection against several common pump-system problems.
- Dry running
- Overcurrent
- Motor overheating
- Excessive cycling
- Abnormal operating conditions
- Pressure and flow faults
These protections help manage the pump but do not replace correct installation, adequate water supply, proper suction design or suitable electrical protection.
CONNECTIVITY
Does the E.SYBOX MINI3 Have App Control?
DAB's current international-generation MINI3 documentation includes integrated connectivity and remote-management capability through DAB's connected platform.
Current manufacturer material also allows groups of up to two MINI3 pumps to operate together.
Australian stock can include different hardware revisions, so connectivity should be confirmed from the actual identification code and supplied documentation if app control is an important purchasing requirement.
Do not assume every MINI3 already in the Australian supply chain has identical connectivity hardware. DAB specifically notes that the same model family can have revisions with different characteristics.
