Direct Factory Wall Hung Toilet with Inbuilt Jet

Overview

This unit combines a wall‑mounted vitreous china bowl with an integrated flush‑jet mechanism that delivers a pressurized spray directly from the rim. The jet is fed by a concealed solenoid valve activated by the flush cycle, eliminating the need for external spray nozzles or additional piping.

Technical Specifications

Design & Jet System

The jet channel is machined into the inner rim during the green‑state forming process, ensuring a smooth transition from ceramic to fluid path. A stainless‑steel AISI 304 liner protects the orifice from abrasion and chemical attack. The solenoid valve is positioned behind the access panel, allowing service without removing the bowl.

Materials & Finishes

The bowl uses a high‑ alumina vitreous china body fired at 1240 °C, giving a water absorption rate below 0.5 %. Surface finish meets ISO 10545‑12 gloss level 7 (≈70 % gloss). Optional antimicrobial glaze adds a silver‑ion layer that reduces bacterial colonization by >99 % after 24 h exposure per JIS Z 2801.

Applications

• Healthcare facilities – reduces cross‑contamination risk in patient bathrooms.
• High‑traffic public restrooms – jet provides effective bowl cleaning with each flush, lowering manual maintenance.
• Luxury hospitality – integrated jet offers a premium hygiene feature without visible hardware.
• Industrial washrooms – resistant to cleaning chemicals and impact loads.

Installation Considerations

Mounting requires two M10 anchor bolts set into a reinforced wall stud or concrete backing plate. The rough‑in distance from finished floor to outlet center is 220 mm ± 5 mm. Water supply pressure should be maintained between 0.2 MPa and 0.5 MPa to ensure consistent jet performance; a pressure‑reducing valve is recommended for fluctuating mains.

Maintenance & Service

The jet orifice can be inspected through a removable snap‑in cover; cleaning involves a soft brush and neutral pH detergent. The solenoid valve has a rated life of 500 000 cycles; replacement kits include valve, sealing O‑ring, and mounting hardware. No special tools are needed beyond a standard 5 mm hex key.

Quality Assurance

Each bowl undergoes dimensional inspection using a coordinate measuring machine (CMM) with tolerance ±0.2 mm on critical mounting holes. Jet flow is verified on a calibrated test rig; units outside ±10 % of target flow are reworked. Final visual inspection checks for glaze defects, cracks, and foreign inclusions under 10× magnification.

Customization Options

• Jet orifice size (1.5 mm, 2.0 mm, 2.5 mm) to adjust spray intensity.
• Flush volume presets (3 L, 4.5 L, 6 L) via interchangeable flow restrictor.
• Alternative glaze colors (white, ivory, light grey) produced with inorganic pigments.
• Optional integrated UV‑LED module for additional disinfection (requires 24 V DC supply).

FAQ

Can the jet flow rate be adjusted after installation? Yes, by replacing the flow restrictor cartridge located behind the access panel; no disassembly of the bowl is required.

What information is needed for a quotation? Provide wall thickness, mounting substrate type, desired flush volume, and any custom glaze or jet size preferences.

How are units packaged for export? Each toilet is placed in a double‑wall corrugated carton with foam corner protectors, then stacked on a pallet and stretch‑wrapped. Cartons include a moisture barrier liner.

What is the typical production lead time? Standard configurations ship within 3‑4 weeks after receipt of purchase order; custom glaze or jet sizes may add 1‑2 weeks.
