MODEL 6880: BLASTMASTER™ AIR FLOW UPGRADE KIT
MAXIMUM AIRFLOW VELOCITY PACK
Push your pneumatic horn architecture to its absolute mechanical thresholds with the premium Kleinn Model 6880 BlastMaster™ Air Flow Upgrade Kit. Explicitly engineered to unleash immediate airflow scaling, this modification package is designed for Model 630 horns and can be used to significantly overhaul Model 220 train horns to make them up to 30% louder. By providing a dedicated manifold feed structure, your individual horn trumpets no longer have to share a restricted secondary air volume feed from a single valve—boosting your system to a mind-blowing decibel output.
ELIMINATE AIRFLOW BOTTLENECKS
The core philosophy of the BlastMaster™ package is simple physics: more air volume delivery equals massive acoustic power. The Model 6880 ditches standard restrictive supply layouts by feeding a massive, oversized 1/2" high-pressure primary air line directly into the multi-valve cluster. Paired with two high-performance Model 307 "chrome" solenoid valves, each horn trumpet gains an unhindered, continuous path to immediate air tank pressure for a devastating and highly authoritative blast profile.
Why Upgrade to the BlastMaster™ Kit?
- Isolated Solenoid Plumbing: Dedicates a high-performance electrical air valve to every individual trumpet, ending airflow sharing bottlenecks completely.
- Upgraded 1/2" Air Feed Line: Scales up total cubic feet per minute (CFM) from your air tank to achieve instantaneous burst times and deep acoustic notes.
- Premium Chrome Valves: Includes two (2) high-velocity Model 307 chrome-plated solenoids to flawlessly integrate into existing system brackets.
- Up to 30% Output Increase: Maximizes immediate sound output intensity, creating an unmistakable, commanding street presence.
THE VERDICT: The definitive choice for maximizing classic multi-horn velocity. The Model 6880 introduces an unconstrained 1/2" delivery pipeline and a dedicated triple-valve configuration to ensure your air horn system strikes at its true peak acoustic threshold.
⚠️ Important Fitment Verification Note
Before finalizing your upgrade order, please perform a physical inspection of your existing air horn manifold assembly to verify valve styling:
- Chrome Solenoid Systems: This Model 6880 BlastMaster™ kit is designed specifically for systems utilizing the classic **chrome-plated Model 307 solenoid** valve.
- Brass Solenoid Systems: If your system features a newer, all-brass **Vortex™ 6 solenoid valve** (standard on model configurations since 2017 or showing the brass valve on the retail carton layout), you must order **Part Number 6885 Ultra BlastMaster™ Upgrade Kit** instead.
What's Included in the Box
- Model 307 Solenoids: Two (2) high-performance chrome-plated 12V electrical air solenoids.
- Upgraded Air Tubing: One (1) section of high-pressure, oversized 1/2" pneumatic air line.
- Plumbing Hardware Pack: Complete master selection of required compression fittings, junction adapters, and auxiliary tubing.
🔴 PRO TIP: Balance your upgraded pneumatic speed with clean electrical power distribution. Because you are now firing three high-performance solenoids simultaneously, protect your circuit pathways by routing your trigger lines through an isolated 40-amp fully sealed automotive relay like our Kleinn Part #340 to completely shield your cockpit activation buttons from electrical spikes.

Three Solenoid Relay Wiring Configuration
Operating a triple-solenoid setup requires structured electrical distribution to safeguard your dash switches and ensure uniform current deployment to all coils simultaneously:
- Relay Terminal 30: Connect directly to a fused +12V positive battery terminal supply source (Ensure heavy gauge wire wire-run matching the total continuous amp draw).
- Relay Terminal 87: Split this power output line into a three-way junction run, feeding one positive lead wire cleanly to each of the individual solenoid valve assemblies.
- Relay Terminal 86: Ground this terminal pin out directly to a clean, unpainted chassis frame run or negative battery wire layer.
- Relay Terminal 85: Route this control pin wire line run up to your interior manual momentary cockpit switch or horn ring wire link.
- Solenoid Ground Returns: Gather the remaining secondary wire leads from all three solenoid casings and ground them collectively to a bare metal location.
