Description
Altec AIR ELEC26-C Prefilter Auto Drain
The Altec AIR ELEC26-C is a prefilter auto drain (timer drain) designed to automatically discharge condensate collected in a pre-filter bowl. By removing liquid water before it can carry downstream, it helps maintain consistent filtration performance and reduces the need for manual draining.
Key Features
- Automatic condensate discharge: Helps evacuate water collected by the pre-filter so the bowl doesn’t remain flooded during operation.
- Supports cleaner, drier air delivery: Removing bulk condensate at the pre-filter helps reduce moisture carryover into downstream equipment.
- Reduces routine maintenance: Minimizes manual drain checks and helps keep the pre-filter operating as intended.
- Designed for pre-filter assemblies: Commonly used where a pre-filter timer drain is required on Altec AIR dryer/filter packages.
Specifications
| Model | ELEC26-C |
|---|---|
| Type | Prefilter Auto Drain (Timer Drain) |
| Function | Automatically discharges condensate from a pre-filter bowl |
Benefits
- Helps prevent re-entrainment: Draining collected condensate helps reduce the chance of liquid water being swept back into the air stream.
- Protects downstream components: Lower moisture load helps protect dryers, tools, and processes from water contamination.
- Keeps filtration performance stable: A properly drained bowl helps maintain consistent differential pressure behavior over time.
Installation & Application Notes
- Install on the pre-filter drain port and route discharge to an appropriate condensate collection/handling system.
- Set drain timing based on condensate load (higher humidity and higher run time typically require more frequent cycles).
- Keep the discharge line clear and unobstructed to prevent backpressure that can interfere with draining.
- Depressurize and isolate the filter assembly before servicing or replacing the drain.
Frequently Asked Questions
Altec AIR ELEC26-C Prefilter Auto Drain
▶️ Question: What problem does a prefilter auto drain solve?
Answer: A prefilter auto drain removes the liquid water that collects in the filter bowl so it doesn’t build up and get carried downstream. This helps the pre-filter do its job and reduces the need for manual draining.
▶️ Question: Where is a timer drain typically used in a dryer package?
Answer: Timer drains are commonly used on pre-filter bowls where condensate is expected to collect, especially on dryer/filter packages that specify a pre-filter timer drain as part of the system build.
▶️ Question: How do I set the drain cycle?
Answer: Start with short, frequent drain cycles and adjust based on how much condensate your system produces. If the bowl is staying wet between cycles, increase frequency or open time; if little to no condensate is present, reduce frequency to avoid unnecessary air loss.
▶️ Question: What connection size do I need for a condensate drain?
Answer: Match the drain’s NPT connection to the drain port on the filter bowl. Altec’s programmable condensate drain options are available in multiple NPT sizes (1/8", 1/4", 3/8", and 1/2"), depending on the application.
▶️ Question: What are signs the drain needs attention?
Answer: Common symptoms include water backing up in the filter bowl, persistent moisture carryover, or the drain discharging continuously. Check for debris in the drain, a pinched/blocked discharge line, or a drain that no longer cycles correctly.
