Description
ZEKS NCC3701-D No-Air-Loss Drain
The ZEKS NCC3701-D is a no-air-loss condensate drain designed to remove liquid from compressed air system equipment while minimizing compressed-air bleed. No-air-loss drains typically open only when condensate is present, helping reduce unnecessary air discharge.
Key Features
- No-air-loss draining concept: Designed to discharge condensate with minimal compressed-air loss compared to traditional timed drains.
- Level-based operation style: Typically drains based on condensate presence rather than fixed cycles (helps reduce wasted air).
- Energy-conscious choice: Reducing compressed-air bleed can lower system waste and support more efficient operation.
- Standard power compatibility: Runs on 115 VAC, single-phase power (50/60 Hz).
- Good for variable condensate loads: Well suited when condensate production changes throughout the day or season.
Specifications

Benefits
- Reduces compressed-air waste: Minimizing air bleed can help reduce unnecessary compressor run time.
- Quieter draining behavior: No-air-loss style draining can reduce the loud blast often associated with timed drains.
- More responsive condensate control: Drains when needed rather than only on a schedule.
- Helps protect downstream equipment: Prevents condensate pooling and reduces water carryover risk.
Installation & Application Notes
- Install at a low point with proper piping support and a clear discharge path.
- Route condensate to an appropriate collection point and handle disposal per local requirements.
- Periodically verify proper operation and clean any sensors/valve components if condensate is dirty.
- Confirm electrical supply and any installation clearances before ordering.
NCC3701-D is a strong fit when you want automated condensate removal with minimal compressed-air loss—especially in systems with variable condensate production.
Frequently Asked Questions
ZEKS NCC3701-D No-Air-Loss Drain
▶️ Question: What does “no-air-loss” mean for a condensate drain?
Answer: It’s designed to drain condensate while minimizing the escape of compressed air, unlike many timed drains that vent air during every cycle.
▶️ Question: When is a no-air-loss drain better than a timed drain?
Answer: When energy savings matter, when condensate production varies, or when you want to reduce unnecessary air discharge.
▶️ Question: Does it still need regular maintenance?
Answer: Yes. Dirty condensate can foul valves and sensors; periodic inspection and cleaning help keep performance consistent.
▶️ Question: What power does the NCC3701-D require?
Answer: This model runs on 115 VAC, single-phase, 50/60 Hz; confirm the site power matches before installation.
▶️ Question: Where should I install it for best results?
Answer: At equipment low points—filter bowls, receiver bottoms, dryer drain outlets, and separator sumps—where condensate collects naturally.
