Product Description

Designed for workplaces that serve around 20 users, the AFK-188 is a Vertical Commercial Water Purifier built at Ningbo Aofukang Intelligent Technology Co., Ltd. in Cixi. The unit connects to a mains water line and uses a 100‑GPD RO membrane with PP, CTO, and T33 stages to deliver up to 20 litres of hot and cold water per hour. A 304 stainless steel tank, galvanised steel body, LED display with TDS and temperature readouts, 4‑level temperature adjustment, and a 3‑hour auto‑sleep function are included. The hot‑water circuit is rated at 1000 W and the compressor cooling at 90 W. Production follows ISO9001:2015 standards, and CE, CB, and RoHS records are maintained.

Cabinet & Internal Tank

The outer shell combines galvanised steel side panels with a stainless steel front. The steel has been treated for rust resistance and coated to withstand wiping with standard cleaning agents. At 1450 mm tall and 400 mm wide, the cabinet occupies roughly the same floor area as a standard office water cooler.

Inside, the hot‑water reservoir is made from 304 food‑grade stainless steel. Seam welding is performed by automated argon‑arc equipment, leaving the interior smooth and free of crevices where scale or bacteria could collect. The 20‑litre‑per‑hour heating output is sized to handle peak‑hour demand in a small to medium office—approximately 20 people refilling cups or bottles over the course of a morning break.

RO Filtration & Wastewater Ratio

RO membrane and filter assembly

The four‑stage filtration begins with a PP sediment cartridge, followed by a CTO carbon block, the RO membrane, and a post‑T33 taste‑polishing filter. The 100‑GPD RO membrane is the core rejection stage, removing 95–99% of dissolved solids, heavy metals, and microorganisms. The system operates with a wastewater ratio of approximately 1:1, meaning one litre of concentrate is generated for every litre of purified water. This ratio is fixed at the factory but can be reviewed if feed‑water pressure or quality differs significantly from standard municipal supply.

Display & Temperature Control

LED display showing TDS and temperature Temperature selection buttons Control panel overview

A front‑mounted LED screen provides real‑time TDS and outlet temperature readings. A filter‑replacement icon lights up when the cartridges approach the end of their service interval, helping maintenance staff plan changes without opening the unit.

Four preset temperature levels are selectable via a button on the control panel. The chosen setting governs both the hot and cold circuits, giving users a consistent pour whether they need near‑boiling water for tea or chilled water for drinking. An automatic sleep function triggers after three hours of inactivity, lowering standby power consumption; the dispenser wakes within seconds when a button is pressed.

Where It Fits

The AFK-188 is installed in staff kitchens, small office pantries, retail backrooms, and training facilities where roughly 20 people share a single water point. A mains cold‑water line and a standard 220–240 V outlet are the only connections needed; the RO concentrate drain is routed to a nearby sink or floor waste. The front‑opening door provides access to the filter cartridges, and the compressor ventilation grille at the rear should be kept clear by 10 cm on all sides.

Factory Certifications & Quality

Each AFK-188 undergoes a pre‑shipment inspection that includes a water‑pressure leak test, electrical safety check, RO output verification, and heating/cooling cycle test. The certificates below are held by Aofukang and apply to this model.

The Cixi factory covers 7,153 m², runs 6 assembly lines, and produces over 300,000 units annually. In‑house metal fabrication and injection moulding give the factory direct control over the steel cabinet and internal components. Custom branding, voltage settings, and packaging are offered under OEM terms with a minimum order quantity.

Frequently Asked Questions

Q: How many people can this purifier realistically serve?

A: The 20‑litre‑per‑hour heating capacity and 100‑GPD RO output are matched to workplaces of around 20 people. For smaller teams the recovery time is shorter; for larger groups a second unit or a higher‑capacity model may be needed to avoid waiting during peak hours.

Q: Does the 4‑level temperature control remember its last setting after a power cut?

A: Yes. The control board stores the last selected temperature setting, and the unit returns to that setting when power is restored. The clock‑based sleep function resets after a power interruption, so it will need three hours of inactivity before re‑entering sleep mode.

Q: What is included in the standard shipment?

A: Each box contains the main purifier unit with pre‑installed filters, a drip tray, a user manual, and connection fittings for the water inlet and drain. The first set of replacement filters is not included but can be added to the order.

Q: Can the front panel be removed for deep cleaning?

A: The stainless steel front panel is fixed and not designed for user removal. However, the drip tray, filter access door, and side panels can be cleaned with a damp cloth and mild detergent. The internal water circuit should only be serviced by a technician.
