Guardian G6040
OSHA 29 CFR 1910.151(c) requires suitable facilities for quick drenching or flushing where employees' eyes or body may be exposed to injurious corrosive materials — and that requirement does not pause in cold weather. A standard combination safety shower and eyewash can freeze in winter conditions if it is not freeze-protected, potentially leaving emergency equipment unavailable when it is needed most. The Guardian GFR3110 addresses this with self-regulated heat-tracing cable wrapped around the internal piping, thermostat-controlled to keep water flowing in ambient conditions down to -40°F.
The bottom-inlet configuration makes the GFR3110 the right model for installations where the water supply runs up from below — slab installations, floor-supplied configurations, and outdoor setups where overhead piping isn't practical. Beyond the heat tracing, the unit carries FM, UL, and CSA approval for Class I, Division 2, Groups B, C, and D environments, which can be considered for chemical processing, refinery, and other hazardous-classified applications where the site's classification matches the unit's rating.
Guardian lists the GFR3110 as tested to and compliant with ANSI Z358.1-2014 and the Uniform Plumbing Code. The unit ships fully assembled and factory-tested. Final installed compliance depends on proper placement, water supply, tepid water, weekly activation, annual inspection, and site conditions.

Heat-Traced Down To -40°F
The GFR3110 uses self-regulated heat-tracing cable wrapped around the internal piping, with a thermostat that activates whenever internal piping temperature falls below 75°F. Guardian rates the unit for use down to -40°F. This helps keep emergency equipment operational in cold-weather applications where standard equipment may not be appropriate.
FM, UL, And CSA Approved For Class I, Division 2 Hazardous Locations
The heating cable, junction box, and electrical components are FM, UL, and CSA approved for Class I, Division 2, Groups B, C, and D environments. That means the GFR3110 can be specified for chemical processing plants, refineries, fuel storage areas, and other hazardous-classified locations where electrical components may need to match the site's hazardous-location classification. Most heat-traced eyewash equipment is not hazardous-location rated — verify your installation's classification before specifying.
Bottom Inlet For Floor-Supplied Installations
The 1-1/4" NPT female bottom inlet is the right choice when supply lines run up from the slab or floor below. For installations where the supply line comes down from overhead, see the GFR3100 (top inlet) variant — same station, opposite plumbing direction.
Self-Draining Eyewash Valve
The eyewash uses a 1/2" IPS brass three-way self-draining stay-open ball valve with a 1/2" NPT port that drains water from the spray heads after each use. This matters in freeze-resistant equipment because residual water trapped in the spray heads after activation could otherwise freeze and damage the unit during the next cold snap. The self-draining design helps protect the eyewash function over winter use cycles.
Combination Shower And Eyewash In One Freeze-Protected Station
ANSI Z358.1-2014 generally calls for emergency eyewash and drench shower equipment within 10 seconds of any chemical hazard wherever both eyes and body could be exposed. The GFR3110 combines a safety shower and eyewash on one freeze-protected pedestal, supplied through a single bottom-inlet connection.
Stay-Open Valves On Both Stations
Both the 1" IPS shower ball valve and the 1/2" IPS eyewash ball valve are stay-open type, US-made with brass ball and PTFE seals. Pull the 29" stainless steel pull rod for the shower or activate the eyewash flag handle, and the valve stays open until manually closed — supporting hands-free operation during the flushing period as required by ANSI Z358.1-2014.
UV-Resistant Insulated Jacket
The unit is enclosed in a UV-resistant orange ABS plastic jacket with polyethylene foam insulation. The orange color is high-visibility for outdoor or dim-light environments, and the jacket sections are secured with removable stainless steel screws so service technicians can access the internal piping and heat-trace cable for inspection or replacement without specialized tools.
Which Version Is Right For You?
- GFR3110: Bottom inlet — supply line comes up from below the unit. Best for slab installations and floor-supplied configurations.
- GFR3100: Top inlet — supply line comes down from above. Same unit, opposite plumbing direction.
- GFR3110 with HV option: 240 VAC heat tracing instead of standard 120 VAC. Useful where 240V power is more readily available than 120V at the install location.
- GFR3110 with SSH option: Stainless steel shower head in place of the standard ABS plastic head.
- GFR3110 with GRN option: Green ABS plastic shower head and shell instead of orange — for facilities standardized on green safety equipment.
- GFR3110 with TL option: Adds a heat-trace indicator light so facility staff can verify at a glance that the heat-trace circuit is operational.
- GFR3110 with SP / FP / ALG / PS options: Scald protection valve, freeze protection valve, green LED area light, and magnetically activated proximity (MAP) switch are also available — verify configuration with the spec sheet before ordering.
Alarm Configuration Options
The fourth digit of the model number specifies the alarm configuration. Verify the desired option before ordering:
- 0: No alarm
- 1: Single pole, double throw flow switch for remote sensing capability
- 3: Alarm horn and remote sensing capability
- 5: Light and remote sensing capability
- 7: Alarm horn, light, and remote sensing capability
Sizing / How Many Do You Need?
ANSI Z358.1 generally requires emergency eyewash and drench shower equipment within 10 seconds of any chemical hazard, on the same level, and along an unobstructed path. One combination station is commonly planned per hazard zone, but final quantity and placement should be reviewed against ANSI Z358.1 and your site's safety plan. For tepid water compliance with ANSI Z358.1-2014, Guardian lists the G6040 thermostatic mixing valve as a compatible option (50 GPM capacity, sized for combination units), with the important note that the TMV must be installed in a non-freezing environment.

Frequently Asked Questions
Does The Guardian GFR3110 Meet ANSI Z358.1?
Yes. Guardian lists the GFR3110 as tested to and compliant with ANSI Z358.1-2014 and the Uniform Plumbing Code. Final installed compliance depends on proper installation, location, tepid water supply, weekly activation, annual inspection, and site conditions.
What's The Difference Between The GFR3110 And GFR3100?
Inlet direction. The GFR3110 has a 1-1/4" NPT female bottom inlet — supply line comes up from below. The GFR3100 has a top inlet — supply comes down from above. Pick based on how your facility's plumbing is run. The two units are otherwise identical heat-traced combination safety stations.
What Cold-Weather Conditions Is This Unit Rated For?
Guardian rates the GFR3110 for use down to -40°F. Self-regulated heat-tracing cable wrapped around the internal piping is thermostat-controlled to activate whenever internal piping temperature falls below 75°F.
Does The GFR3110 Require Electrical Power?
Yes. The heat-tracing cable that prevents freezing requires a 120 VAC single phase power supply. A 240 VAC option is available as the HV variant. The unit ships fully wired at the factory; final connection to building power should be performed by a licensed electrician familiar with the site's electrical classification.
Can The GFR3110 Be Installed In A Hazardous Location?
Yes — within the rated classification. The heating cable, junction box, and electrical components are FM, UL, and CSA approved for Class I, Division 2, Groups B, C, and D environments. Verify that your installation's hazardous-location classification matches before specifying.
Does The GFR3110 Require A Thermostatic Mixing Valve?
If installed as an ANSI-compliant emergency eyewash and drench shower, yes. ANSI Z358.1-2014 requires tepid water (60–100°F) for any emergency eyewash or shower used for the 15-minute flush. Guardian lists the G6040 thermostatic mixing valve as a compatible option — 50 GPM capacity, sized for combination units. Important: Guardian notes that the TMV itself must be installed in a non-freezing environment, since the TMV is not heat-traced.
How Does The Self-Draining Eyewash Valve Work?
The 1/2" IPS brass three-way eyewash valve includes a 1/2" NPT port that drains residual water from the spray heads after each use. This helps prevent freeze damage to the spray heads between activations.
What Alarm Options Are Available?
The fourth digit of the model number specifies the alarm configuration: 0 (no alarm), 1 (flow switch for remote sensing), 3 (alarm horn + remote sensing), 5 (light + remote sensing), or 7 (alarm horn + light + remote sensing). Verify the desired option before ordering.
What Power Configuration Should I Specify?
Standard is 120 VAC single phase. The HV option provides 240 VAC heat tracing — useful where 240V power is more readily available than 120V at the install location. Verify available power at the install location before ordering.
Is The Unit Tested Before Shipment?
Yes. Guardian states that the GFR3110 ships fully assembled, factory-wired, and factory-tested.
