Stainless vs Copolyester Jar Specs
Motor Power
The Waring 64 oz BPA-Free Blender features a heavy-duty 3.5 peak-HP motor. This provides significantly more torque than the Waring 48 oz Stainless Steel Jar Blender, which uses a 1 HP commercial motor. Higher horsepower allows the 3.5 HP unit to handle dense ingredients with greater ease. The 1 HP motor is sufficient for standard blending tasks but may struggle with very thick mixtures. If you need raw power for tough jobs, the higher HP rating is a clear advantage.
Jar Material
Jar construction differs between the two models. The Waring 48 oz Stainless Steel Jar Blender comes with a one-piece 48 oz stainless steel container. Stainless steel is durable, metal-safe, and resistant to odors. The Waring 64 oz BPA-Free Blender uses a stackable BPA-free copolyester container. Copolyester is lightweight and shatter-resistant, making it safer for high-volume commercial environments where breakage is a concern. You must choose between the permanence of metal and the safety of plastic.
Capacity
Container size is a key differentiator. The stainless steel model holds 48 oz, which is ideal for single servings or small batches. The copolyester model offers a 64 oz capacity. This larger volume allows you to prepare more drinks or smoothies at once. The extra 16 oz provides flexibility for larger parties or batch cooking. If you frequently make multiple servings, the larger copolyester jar is more practical. For smaller kitchens or individual use, the smaller jar may suffice.
Speed Settings
Control options vary by model. The Waring 48 oz Stainless Steel Jar Blender offers a 2-speed motor with a pulse function. This simple interface is easy to learn and use. The Waring 64 oz BPA-Free Blender features high, low, off, and pulse paddle switches. The additional speed settings provide more precise control over blending consistency. The paddle switches are also designed for easy operation with wet hands. More settings allow for greater customization of texture.
Blade Speed
Blade rotation speed impacts blending efficiency. The Waring 64 oz BPA-Free Blender achieves a blade speed of over 30,000 RPM. This high velocity helps pulverize ingredients quickly. The Waring 48 oz Stainless Steel Jar Blender does not list a specific RPM value in its specifications. Without this data, it is unclear how its blade speed compares. Higher RPMs generally lead to smoother results in less time. The listed speed gives the copolyester model a technical edge.
Dimensions
Footprint and height differ between the units. The stainless steel model measures 10.3 inches wide and 15.4 inches tall. The copolyester model is narrower at 8.5 inches wide but taller at 18 inches. The narrower width of the copolyester blender may fit better in tight spaces. The taller height requires more vertical clearance. The stainless steel unit is slightly heavier at 10.3 pounds compared to 13.2 pounds for the larger model. Consider your counter space and cabinet height.

Frequently asked questions
Is a stainless steel blender jar safer than plastic?
Stainless steel jars are shatterproof and do not leach chemicals. The Waring 48 oz model uses a robust metal container that resists cracking. Copolyester jars, like those in the Waring 64 oz model, are also safe if labeled BPA-Free. Both materials avoid the breakage risk of glass.
Will a stainless steel jar scratch or stain?
Stainless steel is highly resistant to staining from pigmented foods like turmeric or berries. It does not absorb odors. However, abrasive cleaners can scratch the surface. The Waring 48 oz unit offers a durable finish that withstands heavy daily use without retaining food residues.
Does the jar material affect blending speed?
The jar material itself does not change blade speed. Motor power and blade design determine RPM. The Waring 64 oz copolyester model delivers over 30,000 RPM. The Waring 48 oz stainless steel model has a lower peak horsepower. You choose based on power needs, not container type.
Which jar is better for large batches?
The copolyester jar offers more capacity. The Waring 64 oz model holds 64 ounces of liquid. The stainless steel option holds 48 ounces. If you frequently blend soups or smoothies for a crowd, the larger copolyester container reduces the need for multiple batches.
Is a stainless steel jar louder than plastic?
Metal jars can transmit more vibration and sound than plastic. The Waring 48 oz stainless steel unit may feel louder during operation. The copolyester jar in the Waring 64 oz model dampens noise slightly. Both are commercial-grade units with powerful motors that generate significant sound.
Can I see the blending progress in a metal jar?
You cannot see inside a stainless steel jar. The Waring 48 oz model has opaque walls. You must rely on time or sound to judge consistency. The copolyester jar is translucent, allowing you to watch the mixture. This helps you stop blending at the exact right moment.
