Sun-Mar CENTREX 1000 NE Non-Electric Remote Composting Toilet System — NSF Certified, Off-Grid Seasonal Use

Product Description

All the practicality of a remote composting system, none of the electrical requirement. The Sun-Mar CENTREX 1000 NE is the non-electric version of Sun-Mar's Centrex 1000 system — a remote composting toilet designed for off-grid cabins, cottages, camps, and seasonal retreats where electricity isn't available or isn't desired. The composter unit installs away from the toilet in a separate space, connecting via a 4" vent stack for natural odor control. A compatible ultra-low flush toilet (purchased separately) sits in the bathroom above, giving users a conventional toilet experience without a sewer connection, septic system, or power supply. In light to medium seasonal use, the CENTREX 1000 NE can typically hold compost for a full season, requiring extraction only once in the spring — making it one of the lowest-maintenance composting systems in the Sun-Mar lineup. It is NSF certified to Standard 41 and can be upgraded to an AC/DC system with a separately purchased kit.

• Fully Non-Electric Operation — No fan, no heater, no 110V power supply required. The CENTREX 1000 NE manages odor through a 4" vent stack that acts as a natural chimney, drawing air through the composting chamber and exhausting it outside.
• Remote Composter Design — The composting unit installs separately from the toilet — in a basement, crawl space, or adjacent room — keeping the bathroom looking and feeling conventional while the composting process happens out of sight.
• For Use with Ultra-Low Flush Toilets Only — The CENTREX 1000 NE system is designed exclusively for use with ultra-low flush toilets, purchased separately.
• Light Seasonal Capacity — Accommodates up to 4 adults or families of 6 for weekend and vacation use. In light to medium seasonal use, the unit can typically hold compost for the full season with extraction needed only in the spring.
• Optional 12V Fan Available — A 12V, 1.4W fan is available separately for installations where a bend must be installed in the vent stack. Where a bend is required, the 12V fan is required.
• 1" Drain Hose Included and Required — All 1000 series units are supplied with a 1" drain hose, which must be connected to the 1" drain at the bottom left of the unit.
• Convertible to AC/DC System — This system can be converted to an AC/DC system using the AC/DC kit, purchased separately.
• NSF Certified to Standard 41 — Independently certified by the National Sanitation Foundation (NSF) to Standard 41.
• 3-Year Parts Warranty — All Sun-Mar composting toilets are backed by a 3-year warranty on parts.

FAQs

Q: What is the difference between the CENTREX 1000 and the CENTREX 1000 NE? A: The CENTREX 1000 is an electric model with a built-in heating element and fan requiring a continuous power connection. The CENTREX 1000 NE is fully non-electric — no heater, no fan, no power supply needed. The NE relies on a 4" natural chimney-style vent stack for odor control and is designed specifically for off-grid or power-limited seasonal applications.

Q: Does the CENTREX 1000 NE come with a toilet? A: No. The CENTREX 1000 NE is the composter unit only. It is designed exclusively for use with ultra-low flush toilets, which are purchased separately.

Q: Does it need a 12V fan? A: Not normally. The CENTREX 1000 NE does not require a 12V fan for a standard straight 4" vent stack. However, where a bend must be installed in the vent stack, a 12V, 1.4W fan is required and is available as a separate purchase.

Q: How often does the compost need to be emptied? A: In light to medium seasonal use, the unit can typically hold compost for the full season, with extraction needed only once in the spring.

Q: Can the CENTREX 1000 NE be converted to electric operation later? A: Yes. This system can be converted to an AC/DC system using the AC/DC kit, which is purchased separately.

Q: Is the CENTREX 1000 NE certified? A: Yes. The CENTREX 1000 NE is certified by the National Sanitation Foundation (NSF) to Standard 41.
