Technical assessment of Fontana Aviation-Grade Touchless Faucets and integrated 3-in-1 systems — engineered for fleet commonality, retrofit efficiency, and environmental compliance across aircraft and commercial facilities.
1) Integrated 3-in-1 Systems — Faucet · Soap · Dryer
Fontana’s 3-in-1 assemblies combine faucet, soap dispenser, and air dryer into one self-contained lavatory system, reducing penetrations and simplifying maintenance. Designed to minimize weight and wiring complexity, the system uses a shared 12–28 V DC power bus with independent load control and thermal isolation for each function.
System Design Benefits
Unified detection logic using Time-of-Flight (ToF) sensing for synchronized operation.
Reduced plumbing and electrical interfaces—ideal for retrofit cabins and terminals.
Ingress protection up to IP67 with sealed brass or stainless chassis.
Front-serviceable modules with quick-disconnect fittings for line maintenance.
Finish & Certification
Available in brushed nickel, matte black, and gold PVD coatings, each verified for 1000-hour salt-spray endurance and chemical compatibility under DO-160 Sec 23. Complies with ASME A112.18.1 and EPA WaterSense ≤ 0.5 gpm.
Retrofitting older lavatories to touchless operation requires precision design to maintain compliance and minimize downtime. Fontana’s retrofit kits are dimensioned for existing basin geometries, utilizing adaptive mounting and multi-voltage inputs for seamless integration.
Retrofit Workflow
Capture existing dimensions and structural interfaces in CAD/BIM.
Validate clearances for sensor sight-lines and maintenance panels.
Install mounting adapter plates and harness converters (AC→DC where required).
Perform functional and DO-160 environmental validation: vibration, EMI, waterproofness.
Example: Airbus A320/A330 retrofit programs have adopted modular lavatory touchless kits engineered for plug-and-play installation during overnight checks. Fontana units follow similar modular standards and ADA alignment for seat-level usability.
