About Us
Welcome to the Touchless Airline Faucets blog, a research hub that focuses on engineering and specifications and is dedicated to studying touchless commercial faucets used in airports, aviation facilities, and other public buildings with a lot of people.
This platform is not meant for marketing, sales, or getting leads. It exists to record, study, and put commercial architectural tap systems in context with:
- Design and performance of plumbing systems
- Standards, codes, and rules for following them
- Quality of the water, risk of stagnation, and microbial factors
- Maintenance over the life cycle and reliability over the long term
- Human factors and accessibility in places with a lot of people
The focus is on how faucets work as engineered parts of complex building water systems, not as separate products for consumers.
What Are Commercial Architectural Faucets in the AEC World?
A commercial architectural tap is a terminal plumbing fitting designed to work in conditions that are very different from those found in homes or light commercial settings.
The most important defining features are:
- Following North American plumbing performance standards
- Engineered pressure compensation and flow control
- Durable control logic and valve actuation
- Materials checked for contact with drinking water
- Combining plans for tempered water and plans for managing building water
- Serviceability in places where there isn’t much time for downtime
In the AEC industry, faucets are part of the plumbing system boundary, which affects the system’s hydraulics, the age of the water, and health outcomes.
Why Airport and Airline Restrooms Are a Special Type of Fixture
Airport restrooms have a very high use profile that shows how weak some common fixture assumptions are.
Some important conditions are:
- High and unpredictable peak demand during flight banks
- A lot of variation in pressure across distribution zones
- More likely to be vandalized, misused, or turned on in an unusual way
- Limited access for maintenance during business hours
- Greater awareness of public health and water quality issues
In this case, choosing a fixture is a risk-management choice, not a choice of finish or feature.
Architecture for a Touchless Tap System, Including Activation and Control Logic
Most commercial touchless faucets use active infrared sensing and logic based on microprocessors.
Some technical things to think about are:
- The shape and alignment of the sensor beam
- Distance from the basin’s shape to the detection point
- Delay in activation and shutoff time
- Maximum protection for run time
- Modes for cleaning and locking
- Diagnostic signaling and setup interfaces
If the sensor is not set up correctly, it can cause false alarms, higher water use, and unhappy users.
Mechanisms for Valve Actuation
Some common ways to actuate are:
- Diaphragm or plunger valves that work with solenoids
- Ceramic cartridges that are driven by a motor or gears
Each method has its pros and cons:
- Tolerance for debris
- Time to respond
- Using power
- How hard it is to maintain
No matter how they are made, upstream filtration and flushing after construction are important for long-term reliability.
Engineering for Outlets and Discharge Characteristics
The design of the outlet has a direct effect on splash, aerosolization, and how users perceive it.
Some common types of outlets are:
- Devices for laminar flow
- Devices that let air flow
- Spray or multiple-stream outlets
When choosing outlets for busy places, you need to think about how long they will last, how resistant they are to misuse, and how well they fit with the shape of the basin.
Compensation for Flow Rate and Pressure
To meet regulatory and environmental goals, modern commercial faucets often work at lower flow rates.
Design implications are:
- How well the rinse works in cold or warm water
- Increased age of water at the point of use
- Interaction with automated flushing or strategies to reduce low use
When making decisions about flow rates, you should think about the overall design of the plumbing system and the plan for managing water.
Standards for Plumbing Performance
In North America, plumbing supply fittings are governed by ASME A112.18.1/CSA B125.1, which establishes how these fittings must perform and how they are tested. The ASME A112.18.1 Plumbing Supply Fittings Standard defines performance and safety requirements, and products are typically certified through a listing for ASME A112.18.1/CSA B125.1 by the CSA Group to demonstrate compliance.
Lead Content and Effects on Health
Health impacts related to drinking water are addressed through NSF/ANSI standards. NSF/ANSI 61 evaluates how materials that come into contact with drinking water affect human health, while NSF/ANSI 372 establishes limits on the weighted-average lead content of wetted components. Together, these standards help ensure that plumbing products do not introduce harmful contaminants into potable water systems. Reference documents for NSF/ANSI 61, Drinking Water System Components: Effects on Health, and NSF/ANSI 372 provide detailed technical criteria.
Requirements for Accessibility
Accessibility requirements for plumbing fixtures in public buildings are defined by the 2010 ADA Standards for Accessible Design. These standards specify how fixtures must operate, their placement relative to walls, and the minimum clearances required to accommodate users with disabilities. The official ADA Standards page and the corresponding PDF provide comprehensive guidance on these requirements.
Water Management and Microbial Considerations
Touchless faucets influence water usage patterns by changing activation frequency, flow duration, and stagnation time, all of which can affect water quality within premise plumbing systems. Certain conditions are known to increase microbial risk, including short and frequent activations, low flow velocities, warm ambient temperatures, and extended periods of low or no use. Because of these factors, fixtures must be evaluated as part of a broader water management strategy for buildings to reduce health risks associated with water stagnation and degradation.
Industry Frameworks for Managing Water Risks
ANSI/ASHRAE Standard 188 provides a structured framework for managing the risk of Legionella growth in building water systems by guiding the development and implementation of water management programs. The Centers for Disease Control and Prevention (CDC) identifies stagnant and aged water as primary contributors to microbial growth and offers guidance for building water systems, including Legionella control strategies, recommendations for checking building water quality, and design considerations for potable water systems through its Legionella Control Guidance Hub and related technical modules.
Main Technical Topics
This research hub tracks and examines a range of technical aspects related to touchless plumbing fixtures. These include the logic and installation of touchless tap control systems, the interaction between the basin and the spout, and different strategies for mixing and tempering water. It also explores power architectures such as battery-powered systems, hardwired installations, and energy-harvesting solutions, along with the role of strainers, filters, and debris management in system reliability. In addition, the site analyzes patterns in specification language and fixture schedules, as well as common failure modes observed in high-traffic restroom environments.
Methodology for Sources
All technical claims presented on this site are supported by authoritative and verifiable sources. These include publicly available standards and regulatory documents, peer-reviewed academic research, and manufacturer technical documentation and specification sheets. This approach ensures that the analysis remains grounded in established engineering principles, regulatory compliance, and real-world product data.
