Our paint filling machines use Net Weight Filling Technology, which is ideal for paint and coating packaging processes that demand high accuracy, robust performance, and the flexibility to handle diverse product viscosities from thin stains to thick architectural paints.
With over 55 years of global expertise in net weight filling technology and over 100 systems installed across North America since the early 1980s, Serac delivers local support from our Illinois manufacturing facility. We are the trusted source for high-quality paint filling and capping equipment.

Net weight filling measures actual product weight, reducing product giveaway that can cost tens of thousands of dollars annually in lost resin and pigment.
Our systems deliver 0.1% accuracy (±1g per kg) regardless of temperature, aeration, or foam, ensuring you deliver exactly what customers pay for without the safety margin overfill that drains profit margins.

Serac filling and capping machines are designed to handle the full range of closure types used across the North American paint and coating industry.
Versatile Closure Handling:
Reliable Automatic Pail Closing:
Our automated lid placement system maintains consistent performance at production speeds up to 120 containers per minute. Lids are sorted, conveyed, positioned via chute, and gently pressed onto pails without risk of jamming or misalignment. This system supports uninterrupted production runs while reducing manual intervention.
Filling lacquers, oil-based paints, thinners, and flammable coatings demands equipment engineered to prevent ignition in volatile atmospheres. The explosion-proof fillers from Serac are engineered versions of our standard filling systems, maintaining the same filling accuracy and flexibility,with added safety features for Class I, Division 1 and Division 2 hazardous locations.
The explosion-proof configuration adds shielded electronics in pressurized enclosures and fully grounded construction to the proven performance of our standard filling platform. With installations across North American facilities handling volatile products, Serac filling equipment delivers both safety and productivity.
Our engineers will review your product flash points, container formats, and hazardous area classification needs.

Overfilling to stay compliant means “giveaway”—and at $8/kg for latex paint, this cost adds up quickly. Net weight filling is one approach to help reduce this expense.
Sample Case: The Cost of Product Giveaway
*Using assumptions of production & cost
Product & Cost: Latex Paint @ $8.00 per kg
Container: 1 Gallon (~10 lbs / 4.5 kg target weight)
Annual Operation: 300 days/year (6 days/week × 50 weeks)
Production Efficiency: 75%
Daily Production:
Total Annual Production: 9.72 Million containers
Target weight: 4,500 grams (~10 lbs) per container
Based on this production volume, the only variable is the filler’s accuracy:

A note on accuracy: Net weight fillers typically achieve around 0.10% accuracy (e.g., ±4.5g per 4,500g target). This assumes a 3-sigma buffer above label claim to maintain NIST Handbook 133 compliance. Actual performance depends on your specific product formulation, viscosity, and operating conditions.
This is an illustrative example. Actual savings vary based on your specific operation parameters, product density, and filler condition.
The cost of a paint filling machine depends on your specific project. The main factors include:
