PPG Semco® Model 1088 HD Non-Twist Semkit® Package Mixer — Fully Automatic | Pneumatic | High-Viscosity

Complete automatic mixing. Non-twist precision. Heavy-duty performance — engineered for consistent, thorough Semkit® blending across every aerospace application.

The PPG Semco® Model 1088 HD Non-Twist Semkit® Package Mixer delivers fully automatic mixing of filled Semkit® packages — minimizing operator setup time across different kit configurations, eliminating worker fatigue, and ensuring a more thorough, consistent mix from kit to kit. Equipped with a heavy-duty high-torque motor, automatic catalyst injection, a stroke counter, and a polycarbonate safety door, the 1088 HD is the definitive automated mixing solution for high-viscosity aerospace sealant applications.
⚠️ Safety Notice: Always follow applicable safety protocols and manufacturer guidelines when operating mixing equipment. Ensure the polycarbonate guarding door is fully closed before initiating any mixing cycle. Use dry shop air only — moisture in the air supply can damage the pneumatic motor. Refer to the manufacturer's Safety Data Sheet (SDS) before handling Semkit® materials.

Key Features & Benefits

🤖 Fully Automatic Non-Twist Mixing

The 1088 HD delivers complete automatic non-twist mixing of filled Semkit® packages — eliminating operator involvement in the blend cycle and ensuring consistent, repeatable results from the first kit to the last, with zero twist stress on cartridge components.

🏋️ Heavy-Duty High-Torque Motor

The HD motor delivers more power than the standard Model 1088 CE — engineered specifically to manage high-viscosity aerospace sealants and adhesives that would stall or damage lower-torque mixing systems.

🔢 Stroke Counter for Quality Control

The built-in stroke counter tracks each mixing cycle precisely — providing measurable quality assurance data, improving batch-to-batch consistency, and supporting process documentation requirements in quality-critical aerospace production environments.

💉 Automatic Catalyst Injection

Automatically injects catalyst for injection-style Semkit® packages — eliminating manual catalyst introduction steps, reducing setup time, and ensuring precise, repeatable material ratios with zero risk of operator error.

🛡️ Polycarbonate Safety Guarding Door

The integrated polycarbonate (PC) guarding door provides a clear, durable safety barrier between the operator and the mixing mechanism during every cycle — meeting industrial safety standards while maintaining full visibility of the mixing operation.

💨 Fully Pneumatic — Non-Electrical

Operates entirely on 75–90 PSI dry shop air at minimum 3 CFM — no electrical power required. Ideal for production environments where electrical equipment poses a risk, and for facilities with existing compressed air infrastructure.

🔧 Single-Switch Multi-Config Setup

A single switch adjustment enables seamless mixing across five common aerospace Semkit® configurations — minimizing operator setup time when switching between kit sizes and dasher rod lengths on the production floor.

🎯 Kit-to-Kit Consistency

Full automation combined with the stroke counter ensures consistent, thorough mixing from kit to kit — eliminating the variability of manual methods and guaranteeing uniform material properties for reliable, quality-compliant application performance.
